So Basically, my set up has moved from having a Shadow Priest and a Resto Shaman to a Holy Priest and an Elemental Shaman. Elemental Shamans are like freaking candy. Can't get enough. I did lose Replenishment from the Shadow Priest, but gaining it from my Ret Speced Pally tank, has made up for it, as well as giving me 3% haste across the board. The holy priest still needs some work, but I'm sure he'll do much better group healing than the Shaman, who did Ok, but had issues when it came to the whole group taking damage. (He still healed through fine on melee AOEs)

As far as raid wide buffs go, I've gained 5% spell Crit, 3% haste (basically a Boomkin without the boomkin) at a loss of 3% spell hit, and the shaman is much better at maintaining his damage than the Shadow Priest who had to wind up and build DoTs, and I was clipping his Mind Flays as well. In their previous spec gear, I was still pulling 2k more damage raid wide as well. It will be interesting to see how much that can get upped with some proper gearing.

I did end up speccing my druid back to Resto. I just lost too much healing power to really justify some DoT damage and 3% spell hit. Granted, I REALLY miss that hit, but I missed the healing even more.

I fully expect Ret tanking to catch on once Dual Specs come out. Its just crazy how much extra damage it brings for a relatively minor drop in Survivability. That survivability may be key in some fights, and I need to explore that more, but right now, I'm still impressed.
