Yup DoK, its something that should be looked at seriously by the PTB. Some "ground rules" should be considered, though.
How much bombage to degrade a hanger 1 step? Personally, I think it should take 3 fighters worth of ord to drop a hanger down that first step, and take LA7, Spit16s, P51Ds and the other 7 and under ENY planes out of the mix. That translates into about 4800 lbs plus I believe, including rockets that may be carried. Of course, ALL hangers would need to be hit to drop the effectiveness of the field, so perhaps 1 fighter load could drop 1 hanger 1 step?
Dropping it 2 steps....step it up linearly, or base it on likely damage done by a certain amount of aircraft? How much damage should a box of lancs be able to do, drop 2 hangers to minimum? Dunno...have to think it through.
End results of something like this would be MUCH more than simply high ENY allowing fighters to up regardless of hwo much tonnage is dropped. It would take coordination and teamwork to drop all the hangers the same degree, it would take tactics and strategy to new areas, and thats a GOOD thing....the need for cooperation KILLS griefers

Hardening a few of the ack guns should follow the same idea. Dropping a 500 pounder dead on should kill any single field defense item though.
Also note that if something like this is put into effect, STRAT can be reenabled to mean something, like longer repair times for the hangers. Since the base will be able to up some kind of fighter defense even in the worse case, there's no reason to nueter strat.
Hell, its late, and I jsut came down here to have a cig. Should know better than to even check the damn board ...
