How do you avoid wiping ininstances?

[MongoJerry]

If you bring a paladin along (and they don't get caught healing like I seem to always do) they can use divine protection, run to a cleared area and then divine intervention to remove themselves from all combat for a set time. THey can the rez the party.

Shamans can also self-rez, although they get rez sickness for a ridiculous 10 minutes after they do it.

As the party's priest, there is one way to lose aggro completely -- running out of the instance if the portal is close enough. Sometimes, I've faded to get mobs off me and ran for the exit while the rest of my group valiently provided the distraction I needed to get away.

Also, sometimes you know things are going to go badly right off the bat -- before you even get any aggro. Sometimes, you just have to back off, let the puller or any others who foolishly engaged in battle die, and then rez afterward.
