So, goal is to get people to use matchmaker for balanced games instead of custom games. Current method - force people to use matchmaker to balance by hiding ratings. I don't think this is a good idea but I won't bash it. Instead I'll give some positive feedback how the matchmaker system can be improved enough so people want to use it voluntarily:
(Apologizes if this is already planned)
* Make it possible to choose what map to matchmake + some options (fullshare etc).
* Show how many players currently are searching for teamgames. Show it like a custom game with N numbers of players currently searching. That way you know if someone currently wanting to play a teamgame in a certain map. Otherwise you can have to wait forever. People dont caring about map can end up in same N players pool.
* The number shown of people searching should be players in your own rating interval, with the interval increasing the longer you wait - so you get a game going.
* Dont balance map positions, just teams.
* Tone down regular custom games (subtab?) and make it more obvious how to start a matchmaker custom (maybe move matchmaker closer to the other matchmaking / create game stuff)
