If so here is an easy way to complete this quest is to kill Korrak in Zul Drak (Northrend).
Get your quest from AV, thn head to the Amphitheater (a ring of blood style quest).
Assuming you have not done the quest before you should easily be able to kill Korrak, next AV game collect your weapon
Little tip, if you have already done the Zul Drak quest, party sync with someone who hasnt, it shoud allow you to do it again, just remember to leave party sync once Korrak spawns.
