Azeroth has lost another one of its chief architects to a rival game set in the same universe. World of Warcraft Lead Quest Designer Dave Kosak announced on Twitter that he is now with the Hearthstone team. His departure from the WoW team is the latest in a string of high-profile vacancies that the MMO has suffered this past year.
World of Warcraft pushed out a hotfix yesterday that made small adjustments to several classes, allowed for feasts to be placed inside PvP instances, and touched on the Kirin Tor emissary quest bug.
