It's not PVP, and it's not much of a fight, but there's no other videos I can see of 5xpriests so I put a short video up of me completing the quest to kill teribus in terrokar . It's only meant to show burst DPS from 5x lvl 65 shadow priests in quest greens (about 400 +dmg) - not much else.

If I hit some BG's, i'll post that too
