I ran my ten dungeons as a healer with a WAR tank + two ARC. I always thought Stone Vigil was a longer dungeon so I didn't run it. Brayflox is super easy though. The biggest threat is your characters getting locked out of boss battles. The trash simply consists of hitting Engage and tossing a heal or two while stoning things. Bosses were pretty much the same but with the odd Disengage/Engage to get them away from the boss room gate.
