Actually, I do man boat guns, often. I think its a blast. And when in a bomber, I often ask a squaddie to gun for me, and I will gun for them when they ask.
You are right, in 1944 there wasn't AI. But in 1944 there was a very large pool of men that could be required to man guns. Note, I said "large pool" and "required". We dont have either of these options in AH. Not many will man guns for ships or planes that arent right in the heart of a battle, nor can anyone be required to do it. In lieu of these limitations, we have to have computer manned guns.
I would love to see all guns manned by real players, but I am convinced it is not realistic to expect it. Right now it is hard enough to fly a buff without a gunner. buffs dont have AI, and on a bombing run they are sitting ducks. The pilot either becomes his own gunner, or he bombs.
Again, I will state that I think removing the auto gunners from the ships would be a bad move. It would make the ships too vulnerable.
humbly,
