Please show rating changes in replay vault

@blackyps

Let me reply to your ideas one by one.

First, +1 for victory, -1 for defeat and 0 for draw is inaccurate. For example, in 1v1 ladder, if I am always matched to opponents rated 200 higher than me, and I get +15 for victory and -5 for defeat, I only need a 25% win rate to hold my rating. This makes a lot of sense because the rating system thinks my probability of winning is only 25%. If I win 2 games and lose 6 games, my rating won't change because my performance meets the expectation. However, if I get +1 for victory and -1 for defeat, I will lose 4 scores, which is inaccurate.

You may argue that we won't be always matched to opponents with lower ratings or higher ratings, but in fact this usually happens. Sometimes I only meet lower rating players one day, and only meet higher rating players another day, because there are few people (sometimes only 1 or 2 around my rating) playing 1v1. So the +1/-1 score is inaccurate and unstable, but the True Skill rating doesn't have this kind of inaccuracy and instability, just like the example above. Therefore, the True Skill rating is much better for us to evaluate our performance and track our progress. Please don't hide it.

What's more, this problem won't be solved even if we consider longer periods of time. If you open https://faforever.com/leaderboards , you will see there are players that have played thousands of games but their win rates are not very close to 50%. Let's take StormLantern for an example: He has played 5065 games but his win rate is only 42.8%, which means the average points he won from each victory is about 1.336 times the average points he lost from each defeat, so we can infer that he met opponents with higher ratings more often. If we uses +1/-1 score, his skill will be underestimate. This is not only inaccuracy, but also incorrectness.

By the way, I don't understand your sentence "You will then get extra points for each win until you are promoted to the division you are supposed to be in". Do you mean I will get two or more points for each victory if my rating is higher than my division? I think this is only a rough compensating and doesn't fix the inaccuracy. If my guess about the meaning of your sentence is correct, I can provide more explanations.

This reply is long enough so I post it. I will reply to your other ideas later.

Yes. In your case, being always matched with higher rated opponents, you would slowly lose score until you drop down one division. You would then get 2+/-1 for each win/loss, stabilizing you. You would maybe float around the edge of these two divisions because you will lose this bonus once you are promoted again and the cycle begins from the top.

This might seem inelegant, but it's highly unusual that you get consistently matched with people of significantly higher rating than yourself.

I'm wary of the winrates in the leaderboard because we had database problems with reported wins in the past, so the reported winrates can be inaccurate.

@blackyps

You said "You gaining 12 points after a win doesn't mean that your skill improved by 12 points." I agree with this. But if we review more games in a longer period, it will be meaningful. For example, if I was 900 one month ago and 1100 now, I can know that I made progress, and I can also know the main reason from rating changes. Maybe last month I usually lost to lower rating players because of a certain mistake, which greatly lowered my rating, but now I don't make this mistake. Maybe I was not able to defeat higher rating players, but now I am able to do that, which has significant contribution to my rating. This example shows that rating changes are meaningful.

Let me talk about an example unrelated to this game. When I was in high school, after each math exam, the teacher would tell us the average score of the whole class for each question. In this way, each of us can know whether he is doing better or worse than the average for each question. Perhaps a certain question is very simple, and we should not make mistakes. Perhaps a certain question is difficult, so doing half of it correctly is good. Based on the comparison with the average score, I can know which questions I did well and which ones I didn't do well, so that I can pay more attention to those questions that I didn't do well. This example tells us that providing us with more information can help us make better progress. Playing games on FAF is also like this.

For example, if I was 900 one month ago and 1100 now, I can know that I made progress, and I can also know the main reason from rating changes. Maybe last month I usually lost to lower rating players because of a certain mistake, which greatly lowered my rating, but now I don't make this mistake. Maybe I was not able to defeat higher rating players, but now I am able to do that, which has significant contribution to my rating. This example shows that rating changes are meaningful.

Then you would also be two divsions higher, for example from Gold III to Gold I to reflect this indeed meaningful change in your rating

Thank you for your answer. I will talk about two problems here.

The first problem is that even with the mechanism of "get 2+/-1 for each win/loss", our league system can not become a good tool to track our progress. True Skill rating is much better. This mechanism only gives a rough compensation, but doesn't fix the inaccuracy. When I win a game, my score and rating both increase, but I can only see my score. The rating change is invisible, but it does have an effect. When my rating reaches the range of next division, I will get 2 points for one victory, which is its effect, but it's delayed. If I reach higher divisions after some games, it's difficult for me to know how much each game contributes to this result, because rating changes are hidden. Therefore, hiding rating changes does not make the problem simpler, on the contrary, it only makes the problem more complex.

The second problem is that, one reason for hiding rating changes is because some people have questions about them, so you decide to display a simple thing instead of ratings, right? However, the division system heavily relies on the rating system. Players may ask questions like "Why did I win 2 points instead of 1 point last game?". Therefore, we won't actually solve any problem, but introduce more problems because we introduce more concepts and mechanisms.

Yes, but I don't know how much each game contributes to this result. I don't know whether it's mainly because "last month I usually lost to lower rating players because of a certain mistake, which greatly lowered my rating, but now I don't make this mistake.", or "I was not able to defeat higher rating players, but now I am able to do that, which has significant contribution to my rating", or I have made general progress so I have higher win rate against different players, or other reasons. The details are all hidden, so it's harder for me to analyze the reason.

All those reasons you quoted have basically nothing to do with rating. If you lost because you made a mistake, you catch it regardless of rating. Higher win rate against different players also doesn’t have anything to do with their rating. If you keep beating players, you will get a significant contribution to rating. Again, whole point of trueskill is a 50% win rate. And no, the win rate stats on the leaderboard are just terrible data and shouldn’t have been there in the first place because of problems in how game results were recorded on FAF.

I do not understand this mentality at all. Are you saying you just don’t analyze losses as much when a player way worse than you wins? It doesn’t matter that he played better? All that matters is whether he has a higher trueskill?

Whenever I’ve watched replays what rating gives me as a barometer is when to expect the worst mistakes combined with whether I can expect the player to bounce back from said mistake. Plenty of 1800+ players screw up starts, but it’s something like putting 1 or 2 too few engies on energy production. An 800 just forgot to scale power after 5 pgens. Sometimes a 2000 forgets too, but they recover from it using the tools available to them much faster which may or may not enable them to still keep pace in the game depending on the mistakes of the opponent. The fundamental error is still there to see, though.

I'm just giving an example. "consistently matched with people of significantly higher rating than yourself" is a bit exaggerated. But in my last 20 1v1 matches, there are only 4 games (20%) that my opponents had higher rating than me (opponents are Aranei, Maximbes, Ternencebroad and Mielus), and there are 16 games (80%) that my opponents had lower rating than me. And it is obviously lower in average.

In 1400+ ladder it is quite common to match with a player 200 or even 300 rating above or below yourself. Then, because no one else joins the queue, y'all proceed to play a 10 game series

One issue is that the points required to change division is so high, and FAF games take so long, that now there doesn't feel like there is much progression. You win 5 games in a row, it takes 3 hours, and your division is still the same. If we remove the numerical rating we need divisions that change more often.

-1

@balfron We have a few dozens of divisions, no reason to have a bloat of them. Rating is good for getting some innacurate but exact number, division is good as a milestone.

@blackyps said in Please show rating changes in replay vault:

Can someone in detail explain to me what you are getting from seeing the exact rating change please? Because I frankly don't get it

Because outside of rating change I can immeditely see rating value. I can see that at the moment of the game 1 player was 1650 and other was a 1230 without need to open a replay. That's a hella important information whenever you're checking some replay, so it should be easily available.

This post is deleted!

Pls give us back rating system.
Its way better than this stupid league system like in cs:go.

rating sistem is quite accurate and fair (when it concerns ladder rating espessially) like in chess, u know. why lichess and chesscom wouldnt introduce "league system" then?? because league system sucks. and it equalise not equal players. with rating system i can always see the difference. between farms f.e. and sladow and so on.

if u suck in chess, u suck in chess and have 200 rating. when u suck in supcom, u suck in supcom and have -200 rating, its fair. frustrating? play sims
(instead of "play sims" i wanted to write "fuck u", but that wouldnt be polite)

I just wanna note that the league system is currently not working.

Yes, we are working on it.

I appreciate the work that contributors do for the game and efforts they make to lead the balance and cultivate community and new player experience.

That said, it's been very disappointing losing the ability to see rating changes in the replay vault, and in-game.

In-game it has removed the ability to strategise about targeting players based on their rating, at least for the moment where the league placements are only rarely displaying. Which I have to ask, if the new system isn't functional yet, why has it already supplanted the old system ? And then even when it is fully functional in the future, the league placement will give us less granular data than the previous numerical rating did.

In the replay vault it, as others have mentioned it was really nice being able to see the number go up especially if you got a big boost when you got lucky and beat a player with a much higher rating than you. I think most people understand that it's a heuristic and not entirely accurate. It doesn't need to be, it does the job reasonably enough, especially averaged over long periods of time. Also, isn't this inaccuracy shared by the league system?

I personally wasn't discouraged by the negative rating I attained as a noob and enjoyed the grind, it felt like a real accomplishment finally getting into the positives. An accomplishment which now feels like its been taken away 😞 And I only got into FAF in the last couple years, I imagine that feeling of loss could be more severe for people who've invested more time.

One other argument I've seen that strikes me as particularly questionable. That the league system will reduce people being flamed by teammates when a higher rating loses to a lower rating.

I mean a) there will still be league differentials. Is this just saying it will obscure, say, a difference of 300 by categorising them in the same league? I guess thats one way of addressing that, but people can still be flamed for being a diamond losing to a gold or whatever so its hardly a comprehensive solution on its own terms. But more importantly b) flamers are going to flame. I don't think this is going to solve that problem to any degree whatsoever. The kind of person who gets in chat to textually scream at their teammates for losing in a video game, like. You can't solve that by obscuring the rank differentials by a moderate degree as this change does. You couldn't solve it by obscuring the differential 100%. They will just find something else to throw slurs about because that's who they are. Trying to design the game so it psychologically engineers such people into not being unhinged is a hopeless endeavour.

at least for the moment where the league placements are only rarely displaying. Which I have to ask, if the new system isn't functional yet, why has it already supplanted the old system ?

Are there cases where divisions of players don't show up even though they should? To my knowledge the system is fully functional. It can be that people don't have a placement yet because the current season started only recently.
