My favorite archetype tends to be Fighter with some kind of mental protection (i.e. High Willpower, great force of will). Because of this I tend to play Paladin or Cleric in DnD, though I generally don't care for their rules, gods or even magic. But since a lot of mental based saving throws tend to be Charisma or Wisdom based, I generally gravitate towards them.
Ideally, I'd just be a simply Fighter who can take a hell of a beating and just get back up.
