Just PvP'ed on my 69 enhancement shaman, and I gotta' say, not much better! Heres how it generally went:
Me vs Rogue: Stunlock, dead.
Me vs Paladin: Epic fail.Basically there all retribution now and for some reason retribtuion is extremely buff now... I hope they nerf it because it was embarassing losing to a retadin.
Me vs Warrior: I won! took me feral wolves and alot of instant casted healing waves but I pulled it off!
Me vs Mage: Well, I have a 22.02% crit chance (which I consider good), and I managed to pop a huge WF crit when I got close enough, I then instant casted chain and won!
Me vs Lock: Fear, dot, dot, dot, leave me at 10 hp, starts to dance, /mock, /mock, melees me with staff, dead.
Me vs Druid: Feral, I pwnt. Resto, took me nine hours but I pwnt. Balance, I pwnt!
Me vs Hunter: Loss for me

.
Yah give shamans another buff jesus... Hell I'd settle for a slight buff on WF for crying out loud!
