This quest is a PITA for me. I want to finish it so my Warlock can get her fiery mount (250g for an epic mount and riding skill is cheap), but no one's doing Dire Maul anymore. It's all about Karazhan this and Heroic whatever that.
Azeroth is dead except for the popular 1-58 quests. No one's doing instances beyond level 58 anymore. There's no reason. At 58 you go to Outland and get Tier 2 equipment from soloable hack'n'slash quests.
I want my mount so bad.
