Right now I have Lightening, Sazh, and Vanille. I'm using Vanille instead of Hope because I want a saboteur, but I'm training Hope in the saboteur ways on the side so he'll replace Vanille soon.

My paradigms are:
Relentless Assault: Rav/Com/Rav
Aggression: Com/Com/Rav
Bully: Com/Syn/Sab
Evened Odds: Med/Syn/Sab
Perpetual Magic: Medic/Rav/Medic <~ When I use this you can bet I'm panicking.
Diversity: Com/Rav/Medic

I like to keep my most-used medic one on the bottom so that when I switch it's a simple matter of flicking the joystick up or down, and they're far apart so I can easily see that it went correctly out of my peripheral vision. I'm picky like that.
