[@Noxious] I would say go with what makes sense with your character the most. For example, when I created London, I was debating going Assassin, Medic, or Saber since each would make sense. Given what I created for her history and personality, it made the most sense she would be the assassin type. If I was able to have 2, she'd be Assassin/Medic. But since she can heal, but it's not her primary focus, I like her being able to help by killing her foes with ease.

For your character, I am leaning towards Archer and Ravager based on what I read. It's up to you though.
