Mine heals me very good for an npc.

I spec'd mine as a healer while leveling my conjurer, and when I started leveling thaumaturge, having a healing NPC stuck to my side really made life simple (and I was pleasantly surprised how easily he kept me topped off) . I'd say the healing and attack specs are the most useful. I don't know anyone who has had much luck trying to make defender actually work like it "should."
