since the update and the reduction in damage caused by rockets on armour you may as well just get rid of planes. you can't have a decent dogfight anymore if there's a single Valentine or panzerflak they just anhialate you and takes far too many hits to destroy them.
All this encourages is for people to sit in spawn and constantly reload their vehicles. I'd say keep the power on the aa but increase the rocket damage power so at least pilots have a chance of hitting the aa vehicles. either this or have a planes only map like coral sea in by 1943 so at least us pilots can have a decent dogfight again.
