i suck small team far more, the weighting is skewed, and i should avoid small games with heavy disparities.
Can go both ways though. People that are better at smaller games would get an advantage there.
The main problem probably is that the system has few information about 2v2 games as most players play large games. I would like to have more ladders, but if that is to work there should also be a way to encourage players to play more varied games. Something like "play in the last 30 days at least 10 2v2 games to show on the 2v2 ladder" (numbers as examples, should probably be a range like 2v2 up to 4v4, etc.)
Not to mention is smaller games you are much more dependent on what "the other player" does. If he is troll that fools around - not much you can do. If he wants to win and listens to advice - different story
