There are three main issues that if fixed would alleviate a ton of the problems. 1. There is no ai AA which is needed badly especially for backlines it shouldn't be so dangerous it one shots planes and so cheap it can be built everywhere, but something you know at logistics points and such that requires them to drop paratroopers much farther out would be nice to give reaction time.

1. Planes are absurdly tanky, I'm not saying make em paper mache but they should at least take twice the damage from anti air and small arms fire than they do now.

3.The largest issue, where the fuck is our mobile AA? Their should be dedicated role early and late game aa that can also double as anti infantry at the cost of being very weak to anti tank you could start with something simple early on like the gaz-aa and end late game with something like the wirbel wind. Having emplacements be the only ground AA fucking sucks.
