I don't mind air being powerful vs ground tbh (and I'm using tanks mainly) makes having air cover essential for large groups of ground forces.
All air cover can do is nit-pick at targets.
In the last week of the beta, I was pretty much playing as an AA Max 60% of the time and in that time I could only manage to kill a few targets per hour.
Everything else, you would get their Armour/HP down to like 10/20% before they would fly away and duck behind something to repair.
Or they would just hover in-front of you while you point blank hit them full on and they just fly and hover like they don't care while they blast you to bits.
AA turrets are totally broken, their damage is so low while air units can just hover in-front of them and unload with their rocket pods and kill it.
Skyguards are a joke, I don't get why they think putting recoil on a mounted weapon was a good idea? That thing jerks like it was an infantry weapon. The ammo mag is too low for all the AA weapons, you gotta reload like 2-3 times or more.
Working in teams helps for sure, but that doesn't happen often.
Puzzles my mind on the logic in that.
