Okay, I'm still leveling my Pally, and I'm currently 65. I have played MMORPG's for a while, but never before played Tank. I'm enjoying it, but I have some questions about being an Off-Tank:

I understand that my job as OT is to pick up the adds. But what about when there are no adds? Am I then essentially DPS? Should I switch into Sword Oath to maximize the damage? Is there any benefit to having me remaining in Shield Oath so I can at least be second on the enmity list?
