I agree with everyone's statements about the balance so far. Other things that need to get fixed are:
-Hit the dirt is way too strong currently.
-Russian at grenades with incredibly long range. Players should be rewarded for mircoing vehicle out of harms way
-German Rifle grenade needs to stop using munitions even if you cancel the action.
-Tiger Tank needs to cost less and pay for itself. It's incredibly uselss at the moment for it's price.
-German sniper needs another ability or a buff as it is very useless at the moment.
