Was it possible to solo vanilla raids by the end of WotLK? Question. Pretty much was it says in the title - could you solo the like of BWL, ZG, AQ and Naxx by the end of Wrath? I've heard that it was possible for people to solo the Scepter of the Shifting Sands by then, so I'm assuming that it included the raids, but what about the later ones? 11.
