To die by fleet ack time after time.
I've already learnt that when seeing nme fleet, turn around, wep, dive, climb, do evasives and...die, everytime. There's absolutely nothing to do. Today at CT I died 3 times by fleet ack, flying above 15kft and seeing fleet too late, fuel hit, BOOM (98% of hits are fuel hits (in D-11), strange). Today at CT I really had it. Didn't see the fleet due the rock solid cloud layer that covered almost whole sicily, so couldn't run in time, ping bang boom! Instant hit through cloud layer (fuel hit of course).
How to change it? Dunno. There's been some "whines" about the field ack, I don't find it any problem compared to fleet ack.
There, 100% pure whine, but I sure feel better now =)
Edit: Taking D-11 to 20kft takes quite some time, and get shot down by fleet ack everytime I enter its guns range unnoticed, sometimes little kind of pisses me off.
