[Bug] Mage Q @ lv 50 doesn't exist

[Souldrinkah]

Last part in the quest chain for lv 50+ horde mages doesn't work, as in it doesn't exist. I finished 2 previous parts but when I'm supposed to get the last one - the quest mark just won't appear. Quest is called "Destroy Morphaz"

Edit: And yeah, how come this isn't fixed already, am I the first lv 50 mage on server to find this out?

Rogue, Priest, Mage and Hunter class quests were added in patch 1.7 (Warrior, Shaman, Paladin, and Warlock in 1.8).
