Anti Air is pointless
In the current state the Anti Air Tank is basically pointless and absolutely no fun to play.
You sit in the same spot on the map and basically use one hand to look for jets, see some yet they are out of the extremely limited range. Once they do come a bit closer, you fire your missile, just for them to pop their flares or dodge behind any building, hill or other obstacle or simply get out of range. Now you obviously want to fire one missile to trigger the flare, then shoot the other ... except all pilots know thats possible and simply dodge them as described above...
Basically your only reason for existing is to pop flares so that your own jets will maybe have a better chance.
In case you actually hit something with them, and it won't just say missed despite the missile being dead on, you have no chance to finish the aircraft with your turret in most cases as the bullets dropoff over range is strong, they fly far too slow compared to actual AA and they don't even do damage, its like hitting a tank with your AK. Genuinely who had the idea that shooting A PLAYER would do only 12 damage??? Maybe try taking a AA bullet and see what happens to a human body. Now obviously it shouldnt be op so that people use it as a rapid fire tank against infantry but come on.. The AA hp could simply be nerfed a lot and in turn you will actually do damage, would certainly increase the fun aspect of playing a high output glasscannon. If you were able to actually be in the middle of the map without the obstacles rendering you useless, maybe the range issues wouldnt be so bad either.
Now the most ridiculous part is that once you do shoot an aircraft, the pilot can always jump out of it, resulting in you not even getting a kill for actually making a difference for once... For jets its maybe understandable compared to IRL (most jet pilots will just suicide anyhow to wait for another jet to spawn)... but helicopters? A ton of people simply drop out of it as soon as they pressed their flares... whats the point even.
As of right now you do not die either while playing AA as you have your smoke, decent HP and forcibly sit far outside any action (because otherwise any tank or engineer will easily take you out once spotted) but you basically dont kill anyone, basically net profit, waste of time.
Now I hope you don't see this as an affront to helicopters/jets. Those have some serious other problems unless you are incredibly good despite whatever hellspawn of unintuitive, delayed controls are used for either aircraft in this game. But I would rather see an actual improvement of both than keeping a broken system.
