I also tryed this spec for a raid on my Shaman. Now it is fun to ramp your spell power up through this build and it is a DPS increase right now in shorter fights. When it came to a long fight like 4 horsemen, or Grobuls the faluts in this spec really start to show. There are large mana issues when you have to DPS on long fights, and 0 Mana = 0 DPS. There is also a Large advantage to the increase Range you get from Deep Elemental right now if you have to move or don't want to get Cleaved from some nasty Drake.

Providing the Buffs to Elemental go Live as they are on PTR we will see a HUGE increase from Deep Elemental as well as some better scaleing. It is yet to be seen if it will over do the crazy Enhance spec but you will get alot more utility from the Deep elemental talents
