I'm running 4 ele shams with DH tank, done all the normals and have done EoA and Violet Hold heroic, haven't tried the others yet. Some bosses are just a constant movement requirement for my shamans, and it suuuuuuuuuuucks. Who else hates violent winds in EoA? But the change did help me a fair bit, trash dies quicker and I am able to dps boss harder through ascendance, so I'm happy. I'm 840ilvl now and don't think I have ever struggled so hard with heroics. Dreading even trying mythics. Will probably have to wait til next major content patch when I'm 900ilvl and just brute force my way through it.

I'm pretty sure this is what most classes are complaining about for the heroic raids, their dps is fine, until they have to move, then it drops like crazy.
