Matchmaker Pool Feedback Thread

@xiaomao is the carry slot not rock? isn't that the 3300's slot? I'm confused. Anyway, opti balance could use some improvement since autobalance proves the task can be done better. Why not use that for tmm instead? As I said, ideally every game has every player of equal rating and the balancer is moot, but the more restrictions, the more players need to queue before games can be found. It would be great if someday it could serve us all perfectly balanced games with little hassle but the priority should be growing it's popularity because that's the only way it can be achieved. Until then you can host custom and enforce rating restrictions with not that much hassle.

None of it explains why custom "all welcome" lobbies need to be unrated.

There was literally 10 minute strat bomber that got ctrlk'ed to just not end the game at that point...

Also, it's a perfect example of game that should of have never been rated.

Looked to me like the better team won in that replay ftx posted, but it also looked like the game never should have had 89% quality as everyone on south team was doing significantly worse than their counterparts and their 4v4 ratings compared to north team don't justify 89%. In that sense I'd say the rating system worked but a bit suboptimally, and I suspect some goofy abused global rating was substituted for 4v4 rating so there was bad data to start with. The rating system adjusted player ratings in the right direction. The lane balance was shit but that can be better and the code already exists, courtesy of Penguin. Why do you think it shouldn't have been rated @Xiaomao? I agree it's not a good match for the matchmaker to put together, probably happened because of bad input data, but the rating system responded correctly, more or less, and adjusted the ratings in the right directions.

#20443714 can you tell me why this should be unrated? I didn't cherry pick it, it's literally the first 3v3 tmm replay i stumbled upon with 2 high and 1 low rated member per team and it's a solution i think would work decently well. Why is this not good enough?

G-great. You picked a game with underrated Voodo stack, full on voice and playing same squad every fucking day be it 4v4 or 3v3.
The 500 rated player you see there is actually 1.1k in 4v4 with his Voodo stack.

You better watch this https://replay.faforever.com/19738422 and tell me this is fine.

Also, this is just sad:

so voodoo's "500" buddy should uhh, grind alone until his rating reflects his skill? that will surely fix the issue right ?

Yes. Just like Grimplex shouldn't be able to play with all these 100-500 rated players in TMM.

Watch the replay and say it straight to my face that it was a fine game of FAF. And that we should encourage more of such game to be had in a ranked enviroment.

will watch, currently ingame though. I just don't understand how underrated players grinding at their current rating fixes the issue. you still get bad matchups until the rating system zeroes in on their true skill and it's no faster if they do so with the same nr of players. My choice of replay might have confused the matter since this is a different issue of inaccurate ratings

@xiaomao i watched the replay. It's not fine. I agree a problem is there. Why are you fishing with this "tell me that's fine" bullshit when that's not what I'm arguing?

That doesn't automatically mean the scorched earth solution is good. assuming the player ratings are representative (since the opposite is just a red herring) my suggestion is to modify the matchmaker to look for teams with similar rating spreads. They're easier to come by than full 2k 4v4 teams anyway since some people don't queue in a group and would affect waiting times far less.

A fix to the lane balance could make that scenario better than it is now.

There isn't a fix because someone semi competent at the game can utterly throttle someone with no idea all the time, forever. The reason the guy is 3300 is because he has some level of understanding of how to win the game and plays dudes with zero clue. For it to "fix" itself everyone on FAF at 1800+ is going to gain like 600-800 rating because that's what they would be capable of gaining by just sitting in all welcome games farming 1v0 games. But people don't do that, because it isn't fun to gank bad players for most of the people of the game. People play relatively close players in TS because those lead to the games which are close and you can actually think about what to do.

This is a problem that exists in every rating system, these distribution algorithms are not good at the utter tails where the difference in 100 rating is a 99.9997% win rate or a 99.9999997% win rate.

"Fixing lane balance" also sucks as a solution because you force boring maps where every slot is facing an equal counterbalance of itself. The fun games are where slots aren't mirrored and one slot has 15 mexes vs another than has 10. It introduces gameplay elements beyond "well my mirror did X so now I do X because we always have the same resources available to us at all times."

Ftx, that was in response to the ridiculous replay you posted with the global rating abuser and the stupid air balance on display. there was a 1400 player on the opposite team that should have been vs white and you can't possibly be arguing that the 1200 vs 1800 garbage that the opti balancer came up with for air was "interesting". Given a bunch of players that don't queue together, autobalance does a better job of arranging a decent game than opti, not least because it also takes uncertainty into account. You also say that some noobs complain when pitted against much stronger opponents by opti balance (presumably a bad thing, since you seemed to think this argument supports your claims), then you go back and defend that as being "interesting". Funnily enough, it's an interesting thing you want gone. Take your pick, you can't have it both ways.

Autobalance doesn't currently support pre-made teams but it's a feature Penguin had already prototyped but got cut, I'm sure it could be brought back.

You want the tails of the distribution to only play among themselves? good luck finding a rated game at any other time than saturday night CET. The tails are too thin with the current player count for that to work otherwise.

@ftxcommando said in Matchmaker Pool Feedback Thread:

The logic of building up to map gen is that lower skill brackets need to "learn the lessons" of some maps in a more controlled environment.

I'd totally agree with you here, except for the fact that many of the 'low elo' maps actually teach completely different lessons than those required for top-level play.
Our discussion of williamson's bridge, and its lack of 'going around defenses' tactics, are important here. Many of the low-ELo ladder maps actually teach the wrong lessons - while random maps would teach better lessons.
(And, also, random maps would remove the advantage given to players than have just played a lot of games, too)

The rest of this discussion (carry slots, etc) is totally over my head, I'm afraid! At the very least I'll offer the data point that I've been given 'air; in every team game I've queued for in the matchmaker (I know this because at the start of the each team game I ask what I'm supposed to be doing!).

The only other data-point I feel might be useful is that a team-game 1000-rating player seems roughly equivalent to a 400 1v1 player.

Again, this is a newcomer's perspective. x

You misunderstand my statement about tails. I’m talking about the individual result of a 500 beating a 1900 or whatever equivalent. Is this a 99.99997% end result or a 99.9999997% end result? Impossible for the system to ever know because nobody is simulating 3000 of these games to normalize the ratings across this disparate of a rating difference.

Though this is mainly a problem when combined with the reality of teamgames basically always being possible to balance at 85% or better and therefore allow this level of farming. Because again, you’re pretty much not facing any equivalent opponent if you’re like 2000 on sentons air with 500 allies but the whole enemy team consists of 1000s.

My proposal of allowing 1000 rating of breathing room effectively means everyone has access to the mean population group, so the issue of games doesn’t really matter. Except if you’re like -500 or 2500, but these dudes should still not really be playing with 1000s honestly.

@spikeynoob you guys did a sweaty t2 air all in vs 1ks smh xD

good evidence for ftx though

I was very excided about "New 1v1 Ladder Map Selections", where was said about the intention of matchmaker team to eliminate very small or large maps and extremely high reclaim maps, and focus on more consistent ladder experience
I was thinking about "no 5x5 (sad), no 20x20 (good), more 10x10 (15x15, maybe?) open palm-ish (gold standard for me) type of maps, no reclaim mountains etc

And now i am extremely disappointed
They indeed removed 5x5 for 1200+ (sad, but doable)
But now from 8 maps i got 3 20x20, so if press a btn i got large map in 37.5% cases
More over, i have no idea how Bermuda Locket (20x20 map with reclaim mountains) can be in the pool where supposed to not be large maps and maps with reclaim mountains
Crossfire canal also, it is again large map, and you can say anything, but you cannot say about any "consistency" in ladder gameplay when this map in a pool. The land paths to enemy bases are non-existing there, so you cannot push with land spam directly, which is maybe fine alone, but not with the fact that navy also fights in thin water tunnels. The crossfire canal gameplay differs from average ladder map very drastically. And this is only the cherry on the cake, it shouldnt be there just because its 20x20.
I cannot say anything bad about point of reach except its size tho (yes, direct land push is impossible, but atleast navy gameplay is "as always"). As with all 20x20, the game length there can be very different than 10x10. Cannot see any sense being 20x20 in a pool where is no 5x5 for "game length should be consistent" reason.

Additional feedback data:
Im 1600 1v1 ladder
here is the tier-list of current mappool:

as you see, the pool overall is not so bad
Bad is the fact that i got 100% of S-tier maps and 62% of A-tier maps deleted just because im in 1200+ bracket
With 37.5% of 20x20 maps in my pool i surelly will press the btn less, will probably just switch to 3v3 where you have no 20x20 in the pool at all (also the pool full of neroxis is very tasty) (lol, why we have 20x20 in 1v1 and dont have it in 3v3)
You gain rating, you get more of shitty maps, i think this is not how it should be working
Veto system would be help, if i could atleast ban bermuda and crossfire it would be good enough (except the map pool of only 6 maps is kinda small). Also in this case you can add couple of 5x5, so 20x20 lovers ban 5x5, and 5x5 lovers ban 20x20, everyone is happy
Without veto system, i think the max map size should be capped at 15x15, otherwise i doubt about any consistency in game length / gameplay.

@etfreeman

You are interpreting the mappool wrong. With 1600 ladder rating you will have 13 maps in your mappool. The misinterpretation is not your fault, the announcement post of the new pool contains an error. It should have been mentioned that you get maps from your own bracket + the bracket below that.

Consequently that means ~30% of your maps will be 20x20 and the rest will be 10x10.

Bermuda Locket and Crossfire Canal are indeed somewhat on the high side in reclaim. The reason for their inclusion is that there are not many suitable alternatives that allow for navy play for 1v1. But I agree that it is not optimal, considering the parameters that were set for this new format. If you have suggestions for other navy play maps for 1v1, that are more suitable, let me know.

Last, I don't think it was ever the intention to exclude 20x20 maps completely from this 1v1 trial format, but I understand your confusion, now that I reread Arch's announcement.

I agree that 30% 20x20 maps might be a bit much. Perhaps we can remove one.

Yeah we'll go for max 3 20x20's instead of 4 for the upcoming pools of the trial.

@etfreeman said in Matchmaker Pool Feedback Thread:

...

Hey apologies for not communicating the change properly. The 1v1 map pool now considers your current rating bracket and the one below it, like the other matchmaker queues. This means that the ratio of 20km maps is approx. 30% (4/13) for the highest bracket. I'll get someone with moderator rights to add that to the map pool post. Regardless, we'll consider decreasing the amount of 20km maps for the next pool.

As for Bermuda and Crossfire, I do agree that they are outliers. However, there's an unfortunate lack of navy maps suitable for 1v1. I'm not sure if we can get rid of maps such as those entirely. We'll take your feedback into consideration though. For what it's worth, note that there's no Ditch, Daroza, Painted Desert, or such maps.

Thanks for the feedback!

(damn storm replying while I was writing!)

Crossfire and Bermuda aren't real 20x20s. I don't even think the used area of Bermuda qualifies as 15x15. They absolutely compare to the settings of 3v3 maps in terms of playable area.
