I'm so sick and tired of joining a losing team with 4 min left of the game. Granted, I get some xp, creds and a couple of tokens, but it won't get me closer to dailies.
Not to mention the huge demotivational effect it has to join those games.
It'd be nice if quitters got a 30 min lockout to discourage this kind of behavior.
(If you g2g, you won't requeue anyway)
