how do you get exp cuse...you know i dont get it...and i think im the only person who got -9 exp penelties

you get exp from winning a game Ie big team battle, and you loose exp from quiting a game before its finished

only lse exp if you quit a team game. actually there is someone with -1000 exp

You get xp from playing any matchmaking game.

That can be Social OR Ranked, either give you xp. You can only lose the XP if you quit out.
