At this moment you only get to play 2v2 games, though the games is best played 3v3 or 4v4 or 5v5. Will that be fixed soon? I think a lot of people don´t like to play 2v2.
And it also would be really nice if people with roughly the same rating will be matched to each other. Cause now when you play 2v2 ,or if you would play 3v3, if youre teammate is a lot worse then the other players you don´t stand a chance. In that case you´re just playing a useless game cause the result is already determined.
