Belt from supremus for my T6 Skyshatter look on my shaman. It's admittedly only been 3 months, but it is really tiresome to go in there, kill 2 bosses and get nothing for another week. Also, BWL 2h weapons for my dk. No axes, no Ashkandi. Naxx has also been stiffing me. No Demise and haven't gotten a chance to even try for Armeggedon yet.
Since 2008 (I believe) when Karazhan was released I have been farming the Sunfury Bow off Melchazaar.
Back then for stats, currently for transmog. And. it. still. has. not. dropped. lol
Started farming do-tharak 3weeks ago in lfr coining every boss. It actually dropped today after about 50loot attempts. I wish blizzard matches item looks more consistently between difficulties tho.
