I was flying around Skettis earlier when I came upon this guy:

Intrigued, I looked him up on WoWiki after killing him. (I'm a Mage :x)

Now according to WoWiki, "The subject of this article was removed from World of Warcraft in patch 2.1.0.". But I just saw him and killed him. Is this a clerical error or are the old rares that were previously taken out back in somehow?
