If the invasion ai will really become so effective that it will really threaten a player... then I applaud you Lothos and I too will say that HOI2 will be one step closer to finishing stage.
BTW, will USA/UK keep invading beaches alone or will they start doing joint landings? Or at least, if one of the powers establishes a beachhead, will its allies REALLY struggle to assist it? Because now they only seem to put a token effort into it. Also it would be nice if allied AI sent send expeditionary forces not only to other AIs, but also to the player, the way it did in HOI1.
And again I ask, will Germany keep invading Yugoslavia and USSR from its own territory only, or will it eventualy learn to use its allied territory for this purpose also?
