First few times, I dreaded going up that hill, because it was just a wild ride to hell, each time. Then, about the fourth time, I ran across a tank who actually:
1)Marked skull and X, on those casters
2)Asked me to Shackle X, as he would draw the rest away to the side of him.
3)Asked each member of the group, one at a time, if they knew of an interrupt they could use on the mobs that weren't shackled.
4)For the one who didn't answer (there's always one, right?), he told them to just count to six, then burn the skull.
He then instituted a "ready check", and I typed that I'd throw out dispells, and silence. He said, "Muchly appreciated", and we started.
This worked like a charm...
Now, I'm not saying that all of this was necessary, on the part of the tank, but I'm almost 100% sure that he, like most of us, had learned all this, the hard way, and didn't want to repeat it...plus, it was very much fun, to use shackle, for once, and see it actually work, for more than two seconds...
