stuka would fill the same roll as the hurri2D in the MA..
fighter/attack planes would be great if a more comprehensive logistics system was included.. more targets and such (in that case, beaufighter FTW)
right now, this game is focused primarily on dogfights, that is the pivot point from what i can see. i like that, but i know there are some that would enjoy other things more, there are the strategy guys.. i would be one if it played a bigger role.. if supply and it's effects were beefed up i think this game would change around that. the barge and trucks dont fill the logistics side of things (but this is an air combat simulation)
AH seems to be in the process of growing from an air combat simulation to a more well rounded war simulation (at least in structure), would help secure a larger customer base. warbirds never had a supply system that i can remember at least we have one modeled.

what planes would work to balance out gameplay? are there any more roles in the MA that arent already filled by at least two or three aircraft? are we wanting planes more for scenarios/how important to business are the scenarios?
