We worked on this briefly last night, but our Holy Pally was having internet issues. We tried it with three healers and with two and the one issue we found in either was that our Enhancement Shaman was constantly getting one-shot by the Stomp. Ideally, next week we'll be in there with four healers and we'll force it to work.
You're Enhancement Shaman can equip a shield, and he definately should if he has to soak. He can also Glyph Stoneclaw Totem to drop down for stomps. A shield+Stone Claw Totem for Stomps and he should only take about 90k damage instead of getting one-shot for 150k. Just make a cast sequence macro that equips a shield, then equips his offhand again. When he starts casting stomp he hits the Macro, and right after it hits you hit the macro again to get the weapon back. Otherwise have him offspec Resto and have the Holy Paladin soak Stomps intead.
What I was wondering... have someone killed it this week already, by letting their tanks solo the stomps? Read in another thread that it was fixed and the tanks soloing took one-shot hits after the fix. We killed it the first night with that tactic 2-healing it, so... someone have tried it this week?
You have to split your raid into two teams, there simply isn't any other way to do it. Five people will be soaking each stomp (or less). The two closest should be taknig hits of around 170k. Rogues are excellent as one of the closer targets as they can use Feint for every stomp to reduce the damage by 50%. Try taking four healers,and having a rogue on each boss (if your setup allows that).
