It’s good to know that they still take care of oldschool stuff. The Hunter Epic Quest for Rhok’delar is fixed, and Nefarian will drop the Mature Black Dragon Sinew.
The good news for level 60 characters is that Nefarian has finally decided to grow some Mature Black Dragon Sinew, so interested players can complete the quest by picking that item up from him in Blackwing Lair.
UPDATE: (Many people get this article after searching) After the Shattering (4.0.3), the whole questline is gone, aswell as the quest items. Rest in peace Rhok n Lhok. Those who got them before patch, can still have the weapons and the quiver of course.
