Main Problem In the Game
The single player community and multiplayer community are totally different and the game is totally different in the two areas. It appears most of the SP guys play Germany because they think Germany is so out of balance. In reality, I played several different nations and found each of them to be far too easy. The AI is just pitiful.
Whereas, in multiplayer, in the 1936 scenario in particular, Germany is very, very difficult to play and in my opinion cannot win if there is a competent and active Soviet Union. Anything changed in the game to make it harder on Germany because of single player competitiveness concerns is simply going to further unbalance the multiplayer game. As it is, a good human France and a good human USSR together in a game usually results in Germany never getting out of the Low Countries and fighting a two-front war of survival.
The situation is a little better for Germany now that manpower costs are halved. Before that, Germany was in terrible shape because it ran out of manpower quickly. In the end, manpower is what will get you against the Soviets. They can just keep building units like crazy, while eventually Germany just cannot keep up, and any quality advantage Germany might have at some point will disappear (not that I agree with a quality difference given Russia's lead in tank tech and large stable of high quality field marshals).
