The Release of the Archivist Class is a joke that was part of Blizzard's 2009 April Fool's Day materials. Other humor of the day included the Starcraft 2 "MetaTerra-tronTron" [http://en.wikipedia.org/wiki/Transformers Transformers] spoof, a World of Warcraft "Pimp my mount" spoof of MTV's [http://en.wikipedia.org/wiki/Pimp_my_ride Pimp my ride], and a "Dance Battles" joke for World of Warcraft which would allow teams to face off other teams in a dance off.
