Guys, 
  
I just reached the city on my first playthrough on PotD but I am not satisfied with my 6 man party. I will restart again with the following setup: 
  
Main Tank: Fighter 
Ranged DPS: Rogue 
Ranged DPS/CC: Cipher 
Ranged DPS/buffer: Chanter 
Ranged nuke/Aoe...: Druid 
  
Off-Tank: (Chanter, Paladin, Priest?) 
  
I just can't decide which class to pick as an off-tank. A second chanter to debuff enemies, buff fighter and summon, a Pala to buff and heal some or a priest. However I have zero experience as a priest hence I can't tell if they are as good off-tanks as chanters and paladin. Moreover I don't know 
  
I tend to take the chanter for the debuffs and summons but then I won't have much heal beside the druid.
