How much focus should I put on these two roles? Right now I have Sazh as my main Synergist and Vanille as my main Saboteur, but I haven't been spending a whole lot of CP on those as I think I should be. I've been mainly focusing on Commando, Ravager, and Medic roles. Are those two important as well? Right now I'm in chapter 4 and I have been finding myself switching to these roles during a battle because some enemies won't take damage until I have Vanille weaken them.
