*sigh* I'll take the bait.
At top tier, the factions are pretty even right now (apart from UKF) it's only as you creep down the skill levels that axis become more powerful.
I actually agree with everything here really, except USF has around the same win rate in GCS2 as UKF. So both factions appear a little problematic. I'm not really sure what makes USF so bad (Havent played them in a while), probably has something to do with the nonlinear teching being so bad for USF.
Okw, Ost, and Soviets play well into each other and we see that in GCS2, all the factions have around a 50-60% win rate. For Ost and OKW these numbers get a little bump b/c of USF and UKFs 30% winrate but thats a USF and UKF issue NOT a Axis issue.
