This is a reminder in case this News from last weeks Cataclysm Beta Build went past you. A player noticed that a Zul’Gurub Achievement has been removed from the game and Blizzard confirmed the change.
Zul’Gurub is a 20 player raid instance, introduced as content patch in vanilla WoW. While raids were typically 40 players at the time ZG was the first raid for smaller groups, basically the level 60 predecessor of 10 man raids today. Epic drops were, aside from Hakkar, the rare exception.
Zul’Gurub provides 3 interesting drops, still. The Swift Zulian Tiger, Swift Zulian Raptor and Tome of Polymorph: Turtle.
Update: new information here.
