In case you ask me, no I dont love it. The A&A 1914 game is an improvement since it have Dogfight between aircrafts before the ground battle. I think a players feeling depends on how much military experience and history knowledge he got. To a 12 year old kid I guess the OOB AA preemptive fire is great. But if you know history, its just derogatory. If a Turn is 3 or 4 months, and a unit represent 500 or 1000 planes, then the OOB rules dont give me the good feeling. And I hardly can find, even remotely, any way to justify it, like imagine the AA gun also represent interception fighters too, that do Dogfight the first day of the campaign, but never show up the next 3 months to kill more planes, even if the enemy planes show up every day of the campaign.
In the real war, over a time span of 3 months that represent a campaign, fighters would dogfight every day and Bombers would get hit by AA fire every day. But I understand that for simplicity reasons and playability, maybe even game balance, the battleboard is designed simple stupid for some reason, maybe to speed up play in tournaments, or what ever.
I dont dare to suggest house rules, since nobody want this thread closed or moved, but IMHO A&A Global would have been better off with an Air to Air sequence before the general battles, like the A&A 1914 game actually has, and on top of that the AA guns should be able to fire in each and every round of combat that also include attacking aircrafts. Using AA guns as fodder is IMHO not only very not historically correct, but at best a gamey way to abuse a rule
