Healing Marrowgar 25

Marrowgar is easy to heal. Basically you only have to heal the tanks, whoever gets the Bone spike, anyone who gets caught in fires, and when he does his Bone Storm (whirlwind). Tanks have him facing them and we stand bunched behind him, and have a ranged off to the side so hopefully not so many fires into the bunch of us. Probably could get away with 6 healers but we do it with 7. 3 on tanks, rest on raid.
