I survived, atleast...well not whole RFC, i wiped, clearing it would be too good But thanks to ElectronDF and this macro;

/castsequence [target=focus-target-target] reset=combat/12 Lesser Healing Wave, , , , Lesser Healing Wave

Ive managed to keep 3 shamans dpsing, while one was healing the guy who had aggro on him. :thumbsup:
Thanks, and for those who are annoyed as hell, like me, keep trying guys, its most satisfying when you kill those things with your own group
