I have been dying to try this but I've been too skeered. My 4 shaman hit 70 3 weeks ago but are still in mostly blue crap gear. My pally is good enough. I think I'm going to go with 7. I have a 70 disc priest (mostly purple stuff) and a 70 Fire Mage (mostly crafted purples) on other accounts I am going to bring. I'll make a post once I try it ^^.
