I see 0 incentive to play a game like path of exiles. Whats the point of grinding good gear when its worth nothing?
In d3 atleast if you found something awesome you would get a lot of gold -> Money. So the hunt for finding those good items was there.
Say what you want about the d3 AH, but without any currency ingame...everything has no value and i see no reason to play the game once completed.
