Ok, I have no idea if this has been suggested before, but here goes nothing.
How about combining ingredients together to make a larger version? 10 small devil scales= 1 medium...10 medium devil scales=1 large?
Might hurt the AH economy a little bit if it was implemented, but I wouldn't mind having a way to put all my smalls and mediums to better use than getting dusty in my bags.
Thoughts? Flames? Slap in the face with a wet fish?
