Matchmaker Rotation/System Comments

Yeah,i don't think there're a casual high rated players in ladder.
At least I haven't seen any,correct me if i am wrong.

@FtXCommando Before @Brutus5000 implements Ladder Pool 41 please get a fix for Emerald Cliffs, it is imbalanced due to one of the Hydros being unbuildable.

Would be nice if there was a requirement for maps to be playtested more than 0 times before they were put straight in the pool, not just for this kind of basic bugfixing but you would get less of it.

New pool is up, no games on Emerald Cliffs yet but the version in the vault and linked the Map List in 1v1 matchmaker is broken.

I'm happy about the decision and logic regarding map pools and division. As a low rated player I definitely don't want huge maps during the low rated divisions, especially since we already struggle on smaller maps.

Adjusting the 2v2 pool by removing 5x5 maps, let me know if this is better or worse (mainly if you're a newer player).

The map pool system is still not working. I've played a bermuda locket game while being under 1800.

It is working, it uses mu instead of shown rating now.

Mu ? What is that stat ? It' would be more intuitive if we could link the stat shown in your post (1800+) to the number we actually see in our profil, rather than a hidden stat we can't see. It's not very important, but i bet i won't be the last to be confused by it ^^

You could just rename your categories. If 1800 Mu = 1600 real rating just rename 1800+ into 1600+ ?

No I think the rating breakdown as it is works fine, im just going to move everything up by 300 instead to reflect player mu. This will still confuse people as mu is not shown rating, but odds are we are going to just toss shown rating as some sort of measure for the matchmaker and instead just give people their mu alongside a placement period for new players prior to them being given a rating.

So essentially, we're in between a systemic change but everything is working as intended.

@cocAurico Yea, there is a bug where the 2v2 queue is using your 1v1 rating when selecting the map: https://github.com/FAForever/server/pull/702. This fix will be deployed during the Feb. 13 server update.

Like FTX said, it also uses your trueskill mean, so not your displayed rating which is mean - 3 * deviation. I checked your ladder rating which is mean 1882 and deviation 65. Since 1882 > 1800, this explains why you got a map from the 1800+ map pool.

Maps should be done by rating, not mu, because rating is known to the players. People should always be able to know which maps they might get.

@arma473 In a perfect world we would have the client filter out the maps for which your own rating is too low in the map pool view, then you don’t need to know what your rating is to get that info (remember one of the goals of TMM is to de-emphasize rating), but of course this will require someone to implement it, so it will take time. Even with that though, you might not be able to get all those maps for a particular match, since the map selection also depends on the rating of your opponents.

And yea, we really want the trueskill value to be an implementation detail, and have people’s skill represented by a league/division. Soon️

Key point is : people should have a clear idea of which map they can be playing so there are not surprised. When I click "maplist" in the FAF client, does it show all ladder maps or just the maps of my pool ? If it's the maps of my pool, i'd say : forget about displaying MU or whatever, just tell people : "check the maplist to know what maps are unlocked to you" and it's totally fine to me.

Map lists in the client display all maps, not just the ones you can get given your mu.

@FtXCommando According to API Salembay and Adaptive Crateria are in the 800-1300 pool (2v2). Is it an API bug or something wrong with picture?

It looks like we have an error and accidentally gave 800-1300 an extra 10x10 in place of a 20x20 they are supposed to get system side. Adaptive Crateria was me swapping the maps last minute and failing to adjust the doc because I felt it was easier to play than Sirgis.

Thanks for pointing it out.

Just as a note because I'm not sure if I mentioned it anywhere, but I've recently transitioned management of the 1v1 pool to archsimkat. Easier to devolve management for pools as they continue to split into various queues and also means there will be people other than me that can handle the technical responsibilities.

On that note, I'm still looking for additional people to assist in curating maps as well as reviewing map pools, so if the concept of having everything you design hated appeals to you feel free to apply. Don't worry though, I'll love your work and that's all that matters!

when will we see map generator in ladder? <:

Read the map gen thread, mainly my last post.

Update:
The map pool brackets have been moved up by 200 as the rating brackets utilize mu rather than shown rating.

This means everything is now <500, 500-1000, 1000-1500, 1500-2000, and 2000+.

Functionally, things should still operate under the shown ratings of <300, 300-800, 800-1300, 1300-1800, 1800+ for players. There will of course be scenarios of players in these shown rating brackets getting “wrong” pools but that’s due to varying deviations.
