World of chel match making.

Lets just go over the parameters in the game if you wanted a balanced matchmade game.
1. Overall playerbase/clubs actively searching for that game mode with that number of players.
2. The Clubs Division.
3. The Clubs total RP.
4A. Your dressing room lobby's combined/average RP. 
OR
4B. Your dressing room lobby's highest RP player. 
5. A server that is manageable for both lobbies. 

People do not want to wait long times to find a game so I think it just basis it on whoever you can find that is searching within a reachable server for everyone. It's also why I say you add a forfeit option or a mercy rule of like 5 goals so the games can end quicker and people have a better chance to find a new game that matches their skill level since those games would go three periods where a mismatch in skill may only last one before mercy rule applies. Many other games have added it and a game that averages around three 7-8min periods should have one as well IMO.
