The AH is flooded by ridiculous cheap items apparently from CE rich players hunting for UVs.
That makes the crafting business a thing of the past, even 3 and 4 star items are selling bellow the costs.
I'm guessing there's no interest in fixing this, since the UV hunters/CE buyers are supporting the game costs.
But in case there's an interest in a solution, maybe limit the number of duplicate equips one can hold?
