Wow garfrost was that easy with rets? With the constant AoE and your only group healing being from divine storm.... Ya I dont see that as a 2.

Edit: I did end up beating garfrost, but I had to switch my druid to resto. I spammed the shit out of AoE heals and I still only lived with one shaman alive. The boss himself isnt hard, its the fucking AoE that eventually kills your group when he knocks them all over the place with the rocks.
