How about some destroyable a/c and/or vehicles on the tarmac, nonusable to players if preferred, or usable till destroyed. Eye candy I suppose, but does add to realism.
Now for the other. How about making the runways craterable to limit/cease flight ops at base. If even non-improved r/w capable a/c try to lift on damaged areas, would make interesting/challenging to be able to lift.
Would help appease the "win the war" crowd, as well as furballers trying to defend from another field.
Maybe make craters "repair" as others do in AH, with time/resupply.
eh, an idea anyway,
