So you want super auto ack to run to or hide in?
I think the idea is to have decent ack to get your wheels up in before someone swoops in to kill your completely helpless plane.
Deacking and vulching kills fights WAY more than M3 resupply does. You can't really call it a fight if the victim doesn't get 10 feet off the ground. We may all agree that it is a legitimate game tactic, but then why isn't M3 resup, which at least requires a minimal amount of skill on the vulchers' part to spot and kill the M3s?
Coming back from another base is the answer for running battles or if you don't particularly care about saving the base, but if it's a quick base snatch the attackers will have the base long before you get there.
I think the basic problem here has been identified: players who claim to be all about "teh FIGHT" are mad because they bring 25 friends and deack a field and circle around it trying to be the first of the 26 to vulch each upper, but the game doesn't force anyone to up on the runway and get slaughtered.
