Field ack is less effective, when manned anyway, than it was in AH I. The adjusted gunnery hit bubble appears to be affecting it as well as in-flight gunnery.
As for ship-ack, it appears to be affected as well. I don't man the 40mms or 20mms, so I can't say for certain that they have been affected by the new gunnery.
The 5" guns on the carriers and cruisers do NOT appear to be affected however...ahem. Love to man them when the nme is "swarmin' an reuppin'" around a fleet.
Carriers do appear to be more vulnerable to air attack, which may result from less effective anti-aircraft fire.
My thoughts anyways.
