I never went into the class expecting to be able to do so. But over time, while questing, I figured out how to solo just about every group quest I came across in Northrend, including the tougher five-man ones. All pretty much thanks to one talent; Masochism. By tanking big, hard-hitting mobs, you can spam Flash Heal on yourself all day long while the DoTs take effect.
My priest hasn't hit max level yet, but being able to do this has led me to wonder just how much we're able to solo. I'm thinking places like MC, Anzu, Heroic UP (to farm the blue drake). How far can we take our soloability? Any priests have some success stories to share?
