Just ran UP normal to get my wifes hunter (76) through it for the coin - I have not yet tried boxing it with the 4 shamans - But my question is:

How do you do the harpoon/gauntlett?

I did the reset, run up, retrigger way - But found it very difficult to get aggro on the tank, and borderline impossible to pick-up harpoons and not to mention run out and shoot.

Do you harpoon with your main/tank? or one of the dps?
