Because this stew is not quite ready let me stir the pot a bit...
I saw Pyro in the MA a couple days ago and asked him about this very topic, he said they wanted to disable bombs when A/C on ground last version, but didn't get to it, and it was planned for the future.
Personally, I agree carbombing is dweebish, and although we are all dweebs, the fact remains that buffs did not arm bombs til well into the flight.
As for base capture, although there appears no easy solution, if I was setting it up, I'd up the required number of troops needed to take a field, as it seems to me 10 Stormtroopers might be good for sabotaging a bridge or possibly a factory, but 10 truppen would hardly be enough to defend against and defeat an airfield's security force. Consider if you will that although you've flattened a field from the air, that many security force personel would be burrowed in trenches and would come swarming out if 10 enemy troops appeared, HELL! if for no other reason than to get payback for the pounding they just recived from the air.
It should be seriously considered requiring a field to be taken by GV's only, and using the goons for capturing refineries, factories and train stations when they appear in future versions.
I realize of course this is impossible until we have roads to move GV's from base to base quickly.
