While I do agree with most on the changes of adding more ack guns to the fields and towns for protection.
I would still like to see the addition of multi-barreled AA guns from the WWII era. Yes, it is nice to hop in one of the manned acks at a base, however it is still a single barrel, slow firing gun. All the planes in the game have mutiple barrels of 20mm, .50cal, 37mm, 30mm, rockets and bombs.
We have to shoot back with a single barrel weapon that is stationary, while they blaze away with multiple barrels and ord.
On top of that, to hit a bomber group with a 37mm gun is virtually useless, they just dont have the reach or the punch.
This (IMO) is where the Flak36 and 5" guns come into play. I believe they would make a great addition to the game and offer some defense against bombers and such.
my 2 cents
