Horde can enter Dalaran with a quest key from a Forsaken magus; the files hold ten new dungeons

Beta files show a quest-based key that grants Horde safe passage into Dalaran, which otherwise attacks them on sight. The same datamine counted ten new dungeons in the client against the four Blizzard originally pitched internally.

Two changes missed the change log: durability loss from spirit healing was halved, and two gear sets were reset to level 1.
