Matchmaking
}}
 * We’ve removed variability in the amount of MMR you gain or lose from a match. This means that there will no longer be matches that give results like +10/-40.
 * Instead of matches giving 25 MMR, solo games will now give 30 MMR and party games will now give 20 MMR. We have more confidence in the impact of a player on the game when they are solo compared to in a party, and thus we are willing to move a player's MMR faster/slower depending on that.
 * We have removed the Fast/Slow queue and replaced it with Ranked Roles and Ranked Classic. To play in Ranked Roles you need to earn Role Queue games by playing matches while selecting all roles--this is unchanged from before. Ranked Classic has replaced the Slow Queue, and it does not let you select roles. We are making this change because the slow/fast queue concept has not been successful in producing good quality games. The end result was slow queue waiting a little bit longer, and then forcing very bad quality matches on the entire player pool. We think it’s a fair requirement to enforce that if you want to have the advantage of playing a specific role, you have to contribute to the matchmaking system by sometimes playing other roles, or just queue role-less as in previous years.
