had a problem with this earlier today...
don't get me wrong i still wrecked them 3v1 while my teammates were flagging and 2v2ing, but that's not the point, unnecessary 3v5 much?
Yeah, a switch team button would be great before a fight, but only if it allows to switch from the team with the higher number to the lower, and not the other way around.
I usually join the team with less players to even it out.
Maybe when its out for apple youll be seeing more :)
