So I had always used a kind wayfarer for my main, but I always kept him tanky because tank stats tend to give the best conversation prompts in events. 

 

I built one in my current build with Strange Mercy and the Sword and the Shepard, and talk about a walking heal machine! I did not imagine those two talents would be so powerful. Between keeping himself up with lay on hands and every other front liner up with the aforementioned talents, I now know I can plan a merc party without a priest, even in POTD. Maybe still need a druid to regen the back line every now and then, but then again the Shod-In-Faith boots might be all I need for them.

You can even go without a druid.  I used moon godlike monk, barbarian with Shod-In-Faith and a Paladin for all my healing in one PotD run and it went just fine.
