Doing away with drones, or perking them, will likely mean the end of level bombing in the MAs. With how quickly hangars pop, unless you had three people all willing to bomb at once (Good luck most nights...) or a LOT of perks to burn (Bombers fall to fighters quite often in this game) people will not fly level bombers.
The last time I did an HQ run, it took 30,000lbs of bombs on that central building. Is this no longer the case?
It was also well over an hour of flight time just to get to the target, with plenty of interceptors in Me-163s. They made it hell, and I know I never even made it to the target... This sounds like inadequate defense to me.
