my 3 man melee shammy group can be ok on some of the bosses on the island i just try and out heal it or run away the only other way is try and keep them stop them casting the bad moves.

But a few fights i end up dead i try and not fight them mods.

i find the fire aoe are a little easyer for my shammy group with http://www.wowhead.com/item=41533/gl...g-stream-totem seems to work for me a little better not sure if you got anything for a group of pallys. But i can say warlocks got to love it here.
