The fact that so many Germans aren't happy is enough.
About same % of german players weren't happy with march deployment patch either saying soviets were too strong so you know...
You can't really have this kind of poll to be accurate without voters having to post their playercards to prove they play both sides to have somewhat objective opinion.
This poll and all similar ones are always "buff us, nerf them, we have it always bad, no matter how good we have it, its always not enough".
