Aye, I spec'd this for fun one three of my shamans. Problem in the raid was. No paladin, no warrior, just about nothing to boost my ap or spellpower in the raid!

Selfbuffed without potential raid buffs makes this spec have lower dps then my elemental spec. I was 2000 overall dps in this spec and 2400 overall in an elemental spec. So I specced back to elemental straight away. :P
