It drops ALL THE TIME! When I play my paladin.
It still has not dropped when I go on my warrior that could actually use it. On the plus side the parry/stam gem finally dropped. Even more importantly, the hunter was only joking when he asked if he could roll on it. I got very scared when I asked why he wanted a parry gem and he said that hunters can parry. Now I need sockets.
In unrelated news, I've now had two people hire me to make Titanic Leggings. It seems people want to get gear ready for their death knights and they're looking to old-school epics for it. Perhaps I should change the focus of my advertising a bit, show off more of my old stuff. Arcanite Reaper HOOOOOO!
It's a shame there are no BoE T1 drops for them in MC, it would make it much easier to get raids going if I could appeal to greed.
