[9.20.1] Matchmaker Changes

9.20.1 Notes   Improvements to the Matchmaker   Now, the matchmaker attempts to assemble the teams considering the roles within the vehicle types: e.g., the Maus is matched against another Maus, Type 5 Heavy, or E 100, while the T57 Heavy is matched against the AMX 50B, etc. However, in some situations, the matchmaking by roles will not be mirrored, e.g. in case of Platoons that comprise vehicles of different roles. Increased the chance of getting ranked at the top of the list for Platoon players. Equal chances of getting ranked in the top/middle/bottom of the list for different vehicle classes (previously, heavy and medium tanks would end up in single-level battles way too often, while SPGs and TDs tended to get ±2 and ±1 setups). Increased the chance of getting matched in a Grand Battle.
