Hi Shepard, hope all is well.
The only points I would say are to do with the ADS and the fire rate.
In other titles the ADS just seemed fluid and responsive where the AA in the new game is very mechanical, whilst I understand mechanical is probably more "life like" its just not as fun to use as compared to say BF4.
The same really with the fire rate, the rate of fire along with the smooth and responsive movement made the AA fun to use and you could actually get kills with however in this version you very rarely get the opportunity to take down an aircraft, 1. because the turret doesn't move fast enough and 2. the cooldown hits way to fast, that's the best way I could describe it really, I'm not well versed in the way of development and change, if you could copy and paste the old AA it would be amazing :)
