I read that Mind increased heals so I was already putting all points there. I have been throwing some heals as backup because some healers are struggling to keep tanks up I notice in recent runs. I am about 80% in on level 29 though, so I will be main heals soon. I am very excited about finally hitting level 30 sometime later today. I expect the learning curve (if any) won't be too bad for me, but we'll see!
