Bug description: There's loot missing from Nefarian's loot table. The loot in question are the class set chestpieces that should drop from Nefarian. If you search the database for the chestpieces in question, its said they're not dropped from anyone/obtained anywhere.

If you go to the link, which is the official WoW-Freakz' loot table, it says Nefarian is only dropping the class set helmets, but you can't find the chestpieces anywhere in the list.
