I have -
A mostly pure 2h warrior - TRP
Cleric 1h w/shield, war, hydro, necro - Lohse
Ranged hunter with some scoundrel - Sebille
Elemental wizard - Pyro, electric, and geomancy in that order - Fane
Fane can heal himself OK with poison spells and wands. With 12+ Pyro and an int over 40 he can two shot some stuff.
I finally ditched glass cannon on my hunter. All the mobs knew she had it and would often take her out for a whole battle.
