I did the typical pally + 4 shammy but for Wrath I'm swapping in a mage and boomkin for 2 of the shammy's. Reason being that I've always had to rely on other mages for water being an all caster group, that sucked. The druid I picked because I want to PvP with her at 80 but the dmg output boomkin wise and synergy with the mage has been awesome. It's been a long time since I leveled my shammy's but it sure feels like these 2 are dropping mobs as fast if not faster than the 4 shaman. I can't wait to see what the mage + boomkin + elem shaman dps is like with all the group buffs. Plus I still keep 2 shaman for tremors and other totem love.

I'm sidelining my warlock (because I just suck with warlock, don't know why), warrior (meh same), and holy priest because the shaman really seems more efficient from a multiboxer persepective and the totems (tremor mainly - I get so screwed up by fear) are just invaluable. Sad though, I really like healing on a priest, just not mboxing a priest.
