He thinks the last legendary we'll have in Cataclysm will be a shield. According to lore (And I'm just going off of the top of my head) he made goblin alchemists smelted him with elementium, creating elementium scales. He thinks in some way you can get one of the scales (or a version of the scales) as a gigantic shield for tanks.
Names he thought of: [Elementium Plated Scale of the Betrayer] or [Elementium Scale of the Betrayer]
