If you're looking for an enhancement shaman to talk to about pvp, try mauro on blackrock. I personally haven't talked to him because I'm not particularly interested in enhancement, but figured someone might want to.

I've come up against him in arenas a decent amount, he used to play as elemental in their 2345 setup, but he's been enhancement for a while. I thought he was quite good as elemental also. One of the very few shamans I've seen with S3 shoulders, and enhancement to boot!
I've been 60 rating short of my purty shoulders and it's driving me nuts :@
