While Auto-Ack does make the game more realistic, I have on more than one occasion lately heard many say that it seems as if the ack had gotten more powerful/accurate which I feel has been the case. Came in in a 190F from about 8k, went into steep dive and as usual started to pick the edges of the AF...before I fired a single round going aroun 450+ I was hit by 2 ack rounds which 1)PWed me and 2)took off half my wing. Has anyone else noticed a possible change in the AA lately???
