Well, this item just dropped recently for me, but it took awhile!
I was trying to get the leather head from Illidan in Black Temple on my monk, killed him over 20 times in a row before it finally dropped, even got one Warglaive in the process. Now I just need the Off-hand.
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.
