As it currently stands one of the more annoying things in game is aircraft successfully engaging and destroying AAA which is supposed to prevent aircraft from attacking your troops. One potential solution I've come up with is to make AAA far more accurate but only against planes that are attacking that specific AAA. So if three planes are flying overhead but only one is attacking the AAA the AAA will only get a massive accuracy bonus against the one aircraft attacking it. This would represent the fact that if an aircraft is attacking a AAA it is flying straight at the AAA making the aircraft a much easier target for the AAA. In addition by simply buffing accuracy against just the attacking plane the AAA will just be much riskier for the enemy to counter with planes but if the planes get through they will kill the AAA just as quickly as they would beforehand.
