Another shift Classic players might want to take note of is how Blizzard is handling the transition from Burning Crusade to Lich King. When Burning Crusade was first announced, Blizzard allowed players to choose whether they wanted to stay in the original World of Warcraft Classic or move to Burning Crusade. While those who opted to stay in the original version can still remain there, this time there won't be an option to keep characters in The Burning Crusade expansion. Everyone who's already in Burning Crusade must move on to Wrath of the Lich King.
