As you can probably imagine I'm mostly focused on PVP, but I do grind heroics occasionally for gear and gold. I don't know a ton about the mechanics of shaman dps or how to gem. I'm also interested in 6 manning some 10 naxx stuff as well as the 5 man icecrown stuff.

My main question is about haste vs spell power. At one extreme I can push 3200sp unbuffed with about 29% crit. Of course I can get haste up pretty high going down to about 2600sp and a little less crit. A little less of everything overall if I have to go for 25 man hit cap.

In general I will be doing 5 man - what kind of stats should I be going for and where do spell power and haste intersect?

Thanks
