From my point of view, this makes playing game as the Alies a bit pointless. Just wait until Germany is weakended, build your forces and then invasion and victory.
Another issue - does anyone have experince to play minor Axis powers (Italy, Japan) and actualy won the war? I mean, defeat SU and the Allies. And have you managed to do it without taking military control of Germany?
I am looking for some minor changes how to make SU weaker for Germany, but only if Germany is played by AI.
