Blizzard has updated their hotfix blog with the latest changes to Wrath Classic. Players are now able to queue for Battlegrounds from anywhere, among other bug fixes.
Players may now queue for Battlegrounds from anywhere, without having to speak to a Battlemaster. Queue up via the Battlegrounds tab on the PvP menu.
Players that are logged off inside a dungeon instance when it is reset will now log back into the nearest graveyard.
