Mine are 84 at the moment. They're not dominating by any means, but I can see the difference between this team and others that I have played. I have a feeling with gear and practice they're very viable for non-serious PvPers. I know others in the community have been running shadow priests in PvP for a long time, I just wanted to add my .02 from an average/below-average PvPer - shadow priests are fun.
