How many purely Ost / Sov players are there? I play both and I suspect most of the rest of us do too.
I play both but not nearly to the extent I play Soviet thats for sure. I am sure most are like me. They will break the cycle to play the other faction a bit but not 50/50 or even 70/30.
That would be my guess anyway.
And I would further venture to guess that alot stick to the same game mode as well and arent aware of the scale of magnitude issues. Such as having so much fuel in team games that certain units can be spammed and harder to counter then they would all alone.
My biggest opinion on how to make COH2 better and put 3v3 and 4v4 in balance would be to scale back what resources are worth in 2v2 and up. That way Soviets cant have unlimited Mines and Germans cant have countless armor losses.
Since most Agree 1v1 is pretty balanced and to a slightly less extent so is 2v2.
