This is very well described. If you are playing a team who is well coordinated, these abilities can have a YUGE impact on the game, enough to swing it in a different direction. When these abilities are called multiple times and spread out properly you can basically cover half the map, making impossible to avoid, even in your base. If Relic limits air abilities per team to one at a time, it will greatly alleviate the impact these abilities have in team games. Ex: if p47s are in the air, typhoon fighters must wait till the p47 run is finished.
Just build OKW flak half-track, which is best AA vehicle in the game, you noob.
Allied airstrikes was never a problem.
