#1 lets use some of those dirt airstrips from the special events arena's in the main arena, adds more realism.
#2 B-29, it was used in 1944 in large numbers against the japanese, therefore it should belong in this game, no matter how good it would be. "perk it if need be"
#3 new maps, new maps are needed, this game is getting stale. use some of the cool scenario maps, anything different would be better than more of the same
