Thought I'd add this to this topic rather than make a new one.
As a warlock, how to bug the Eagle Gauntlet:
1) Start by casting Eye of Kilrogg before anyone starts the event.
2) Send the eye as far up the gauntlet as you can (you can make it almost to the Tempest half the time). The mobs'll kill the eye, then reset.
3) This despawns the lookout.
4) Have everyone run and begin engaging mobs.
5) The lookout should respawn and start the event.
6) Continue to kill enemies. If eagles/mobs from behind spawn, cast Eye again and send it up to the tempest.
7) If it dies (and it will), the mobs will reset, any mobs you've killed will respawn, and all the adds from the gauntlet will despawn.

The lookout will run back again, but the adds will not come.
I've gotten this to work twice and the only downside is you might have to kill the first two mobs twice. Hope this helps.
Oh and yes...you have to re-bug it if you wipe too many times to the eagle.
