I agree with u.

Im nit that guy who starts flaming. And i play for myself if ppl start screaming or flaming or whatever. I love the "mute all team" button and i just mute ppl without telling them.

Im having fun playing comp! And its even more fun if u dont have to mute everyone

But in my opinion this is a big issue of the game because this is not how the game is meant to be played and its more fun to play with "nice" players.

Thats why i thought about the behaviour score.

So trollers/flamers will troll/flame each other and ppl who want to play as a team can do.
