Nefarian, boss of Blackwing Lair

Hello,

Has anyone, more or less recently, looted anything else but a couple of blue items from the last boss of Blackwing's Lair ?

This guy (or dragon), should genreally drop some purple items, such as the T2 chests, which are very useful for Transmo.

I've been there many times, with different characters, but never ever have I looted anything else but some blue items, when all the other bosses, including those of Molten Core drop one or several epic gear items (T1 T2) each and every time.

Is there a problem with Nefarian ?

Thanks

Yeah loot tables for many raid bosses (Blackwing Lair and Ulduar are prime examples) are bugged or haven't been fully implemented.
