We cleaned Molten Core quite a bit faster again. About 8 hours after Lucifron dropped it was Golemagg's turn to hit the dust and cough up ph4t lewtz, leaving Molten Core with only Majordomo Executus and Ragnaros.
By the way, if you want to view stats of any item that dropped for us in Molten Core (and off other epic dropping mobs such as Onyxia) thus far, I've now allowed directory index listing of the loot images directory. You can find it here:
