been out since patch 2.10... the only american guild (that i know of) that has cleared all the BC content is death and taxes.... 3 european guilds that i know of have also done this: nihilum (world first illidan) last resort (second) and curse (third)...i know that nihilum has since kungen (nihilum MT) has 4/5 t6, and last resort has a video of the illidan down on their website...www.lrguild.org...some forums ive seen say that curse has too, havent looked into that yet though.
