Too little window of opportunity, and prolly too much work for them to implement a whole new mechanic at this point, working on the 2 sub-patches and 2.0 and all. . . .

Not a bad idea, though, but I think we already have way too many high-level weapons right now, and most of them people don't use at all.

Dungeon drops from CC,AV,DH, Skirmish, 3 sets of primal weapons, crafted weapons, GC weapons, relics. . . .
