Level 55 Death Knight restriction going away
In what seems like part of an antiquated system that's outlived its usefulness, the Death Knight creation restriction of needing a level 55 character or higher previously on the account is going away. This is mildly significant in that now a new player can create an account, load up a Death Knight, and jump right into Burning Crusade content. But obviously with the level 90 boost, there's more incentive for new players to skip even that bit and go right into Draenor.
At the end of the day, is this really a big deal? Not so much. But it's interesting, nonetheless.
