Unfortunately there is no pet involved with this year's achievement, it's simply a repeat of last year's rewards -- right down to the in-game mail that happily asks you to defend a shattered world. We kind of did that already, Blizzard. We're heroes now, remember? Regardless, the Celebration Package should offer a nice boost to those still leveling, or those in the midst of grinding out reputation with the Black Prince, Huojin or Tushui. Make sure to log on to all of your characters, so you get the Feat of Strength and the accompanying reward for everyone. WoW's 8th Anniversary runs from now until December 2.
