Who- Vazruden and his mount, Nazan. The last boss(es) of the instance.
Important object of interest- [Only registered and activated users can see links. ]. The horn was added to the ledge of the last boss's spawning point, since there are many ways to kill him and some were causing him to despawn incorrectly.
The Exploit- After you have killed Vazruden and his mount, you have several seconds (exact time unconfirmed) before the chest with the loot spawns, and you are unable to do this exploit.
After you have slain the two bosses, quickly run to the horn (you can't miss it) and click. Make sure your group is in on it!
This will respawn Vazruden as he was before you killed him- IE, with his mount. He will agro the same he did when you killed his Watchers.
The Result- An almost limitless source of Reputation with Honor Hold, with any good group.
Please Note-
That once the chest is spawned, you will be unable to re-summon the boss.

Many thanks to-
My guildies who forced me to run Heroic Ramparts over 9000 times this week.
Damn nice. I am in dire need of some HH rep. I'm guessing this rep stops once you pass the Ramparts rep level? I can't remember which it exactly is but I'm thinking honored?
Hellfire Ramparts - Unlimited Rep!
+REP once I can.
