My team are freshly 70. I just tried this. I wiped 3 times, but I started to get the hang of it. What I did was start out in the corner off to the left. I pulled with my tank and started nuking. When he dropped the zone on my shaman I just arrowed forward out of it and kept dpsing. I did this 4 times and the boss died, lol. It was wicked easy that 4th time. I kept groundings and 1 tremor up, btw.
