As a result of running this instance, I have specced for Silence, on my Shadow Priest. I have tried Shackle, and it seems to only work if I'm in the hallway strat, and I'm lucky enough to find a mob that's far away from the tank.
I believe the most crucial part of that fight is for everyone to give extra time initially, for the tank to gather/gain aggro, and if in the alcove, stay LOS, but move out of the corner, and spread out a bit, once the first one or two mobs are engaged.
For some reason, I have not yet gone in there, on my Arms Warrior, even though I run him every day, at least 2-4 randoms. I'm not much of a stance dancer, but I would like to "make a statement" to those melee mobs who enjoy 2-shotting my priest!
I'm not against the idea of having two tanks in there, although fighting the two mini-bosses might be problematic...would be an interesting test.
I may bring it up to my guildies, and friends, to see if they'd want to try it...
