some units just don’t seem to have any nitch.
All the units in AAP40 have a niche, you just have to think about it more. Some are not as sexy as they used to be (tanks, battleships) and some are certainly bought less by certain players, but in general this is representive of history.
This set of unit stats is the best to date.
Why should crusiers be able to be traded with fighters?
the tac bomber rules already give them a clear role and make alot of sence except they are simpler that yours.
I do like your rules for infantry supporting tanks on the defence, except I dont like tanks costing five. tanks are big things that take alot to produce they should be expensive and players should not be able to build stacks of them (unless they are the russian player, in AAE40 the USSR should not be able to buy mech inf and instead can buy tanks at 5.)
