When you play a game, your bronze ranking thing should not be uptaded depending only on win/loss, but also depending on the BRT(Bronze ranking thingy) of the enemy team and of your team. Example: You're mafia with 1.3k BRT and your teammate has 1.3 BRT Town has an average BRT of 1k, by winning you win like 20 BRT, by losing you lose BRT. Pretty much ELO(Look it up).
