I have 5 priests @ 81 (one now 82) - bored of questing I've put them each into a mixed team of tank + 3dps to use dungeon finder.

all the low level dungeons are coming up due to under equipped level 81/82 priest - plenty of 78/79 greens and blues! Also got over 20 volatile air on the run up to the first boss in Vortex Pinnacle. I was also getting JP for a few characters that need it! it was very profitable
