Says the guy who is rank 12 with OKW in 3v3 random and mostly play as Axis.
When I started playing coh2 I played first ostheer, then switched to soviets, in the alpha i mostly played us forces and now I play okw, it's the most fun faction for me and since I cant play that often I don't really care for having a "balanced playercard".
What annoys me, when I go 3vs3, 4vs4 you get 4-6 matches in a row where you do nothing but stomp new players which have ranks with 4 digits or are even unranked, while me and my random mates mostly being top 200 players. Thus I blame the matchmaking.

Just proves my assumption. If you have a balanced allied team you kick ass just like you do with axis, since 0.7 are negligible. It's the same margin soviets have in 1on1, which I consider to be balanced.
