Maneuvering shouldn't help out at all, because it didn't in real life. German flak batteries were given boxes in the sky in which to shoot. No one on the heavy flak guns on the deck were "aiming" at individual planes. In the beginning of the war, they tried "aiming" and it didn't work. Traditional AAA defense doctrine revolves around sectors of fire combined with separate altitudes for different batteries. You make a 3-D box for planes to fly through and hopefully hit some of them. The N. Vietnamese even did it with SAM's, volley firing them towards planes. Watch the videos of the Gulf War and see how the Iraqi batteries keep shooting in one direction the whole time--same thing. Flak (puffy ack in AH) was a completely random thing in ETO, it should remain so in AH. I think it works well in the game, serves its purpose, and visually gets you into the period during play.
