What's best?

Personally I use QR since he's already slow and can trigger specials better on enemy phase. Vantage is on campus for me as well since I'm more player phase with him than xander

QR, with either TA for green mage baiting or Fury for being a better physical wall in general against non-greens. If the rest of the team you'd run him on is solid against all non-greens, then just run TA on him. And probably Reposition so he can pull a glass cannon back behind him after they nuke someone.
