I understand for the realism aspect of the game the AA makes sense right, but this is a combat simulator and some treat it more as a game. If you look at any arma 2 realism units you will see that the enemy does not use lock on AA providing an engaging experience for pilots because it allows them to give cas without a great risk if they are a great pilot, even if the pilot eventually gets hit it is even more engaging with having parts of the heli damaged rather than instantly dropping out of the sky. They either need to change the AA or reduce the amount of squads that have AA it doesnt matter what but something has to change.
