Well, since beta, they've played with the acks alot. At one point, you couldn't even bomb one, it'd kill ya, then, it was toned to the point where 1-man shows were capturing all sorts of airbases(thus, my point of game play).
You still have to jinx as they did historically, and everyone will tell you to fly over the same field defended by ack more than twice was suicidal to say the least, not true in here, very easy to fly over it numerous times. I find it too easy in here compared to what I've read.
If anything, we need more strat elements to combine with the acks we have.
