@Brain:
Transport ships are boring too, however they are a necessary component.
Transport ship peices are not as necessary as you think, most wargames do not have them, because in many ways they are unrealistic, however i would say that they are a tolerable, and even not boring, component to A&A.
It is unreanable to compare transport ships to transport planes in A&A for the reasons Imperious Leader stated above. They would just be out of place and it would not feel like World War Two it would feel like the cold war or modern day. The only time air transports and gliders were used in large amounts were during airborne assualts, so really what we need is a airborne infantry piece not an air transport piece.
I guess hitler tried to supply stalindgrad from the air, but that was just retarded and he wasnt flying in whole divisions of new soldiers.
