True, but no thunderstorm? I couldn't possibly do the heroics I do without that, As well has it proven valuable in multiple 10 man boss encounters. 4x em+ts is a very big AoE!

Plus, I'm raiding with the more casual type of guild and usually 2-3 in the raid that kinda lack and have to be carried, so I am used to utilize more then just pure dps to beat encounters anyhow.

Right now, my dps is enough for all 10 man it seems, I usually top dps in my guild as elemental anyhow. And I expect the shaman changes like, the 17th. I don't think it's worth, at least not for me, to bother speccing and respeccing after every raid (times 3/4).
