If you would like to avoid mistakes made by relic it would be good if you were aware of them like 1sec lt arty for every sniper, I suppose it's not the best idea to give the possibility of exploiting things that has been considered as imbalanced.
I also think that there are some issues with the soviet's final CPs as god of war and sturmovik or whatever it's called it doesn't really matter that you're most likely would not be able to use them again in the game but if used in the right time they could be game breaking like no other. Is there a limit of bombing runs/strafes? if so how many? what's the area radius? Same question for god of war? Does it fall totally random, or hit enemy units? And what's the area of that as it seems to hit preety distant targets.
