Lightning, Fang, Vanille

Up until the end of chapter 11:
Lightning was exclusively ravager
Fang exclusively commando
Vanille Max medic / working Sab

End of chapter eleven actually forced me to use CP points, maxing out:
Lightning Ravager/Commando/medic = 4/4/3
Fang: Commando/Sentinel/Saboteur = 4/4/3
Vanille: Medic/Saboteur/Ravager = 4/4/3

I built my team entirely on causing staggers as much as possible, leveled Sentinel with Fang purely for strength/hp bonuses - Sentinel was something I never used until nearly the end of chapter 12.

Relentless Assault (rav/com/rav)- Staple
Diversity (rav/com/med)- Staple
Aggression (com,com, rav)- Staple
Med/Sab/Sab - Staple

Last two were rotated in / adjusted as needed.
