Check this thread...

Relates to normal, but advice still applies.

I've only done her on heroic twice, but I set all the shammies to the far left... tank the 3 mobs, dps down the elementals, then focus fire on her. 1st hurricane is normally on the tank _> move. 2nd is normally on the shammies, move to the right.

Shammies basically stay as a grp, and a soon as the AOE hits they move either left or right respectively.... Not sure from your post if you are 5 shammies or 4 and a tank, but tactic should still work with elementals.... There is also a vid on the forums of heroic thespia I think, but not sure...

Good luck

EDIT: Zomg you dinged yesterday? and you already cleared 2 heroics????

You dont need my advice then... I need yours lol
