Harder for GV;s I'll agree, but patience and finding the right vantage point will fix that most times.
And it really is not that hard for 2 or more guys to run a bomber sortie that would 80% level the town and the acks. Leaving the GV's free to run in and clean up.
Or 1 good level bomber and a couple of guys in a20's, and a few jabo's should take the town down quick clean and fast.
