In my view there are only two aspects, which are hampering the game (and these are no bugs): These are the already mentioned lack of armor in the M113-series and the overall hitting power of any kind of artillery. The heavy and also the light pieces are too strong against everything - especially tanks. These things have a negative impact on the gameplay. I think it would make sense to reduce the hitting power as well as the accuracy a bit. That's all.
Kind regards
