Zul'Gurub (ZG) is an end game Raid in WoW Classic with some superb item drops (already got my Warlock specific belt and Chest piece) and can be quite challenging if your group don't know what to do in some bosses.
Facing the final Boss Hakkar and his sons for the first time with my new Guild was a quite smooth experience!!
And he's dead..
Probably one more or two runs on this raid because TBC is launching pre-patch very soon and is the main reason i play WoW again.
