Lets try this question instead: For those of you that captured Lightning, which monsters did you use?
I'm guessing COM MED SEN is the way to go. I'm planning on using the Red and Green Chocobos and not sure what SEN I'll have by the time I get the Green but right now I'm still using Pulse Knight.
I did it at a pretty low level I guess, these are my pradigms:
Noel Serah Monster
Com Moster -> Orion
Sen Monster -> Bunkerbeast
Med Monster -> Green Chocobo
Rav, Rav, Sen -> 2-Folow immediately with this to raise stagger bar fast
Com, Com, Com-> 4-When staggered, attack with 3 commandos for max damage
Rav, Com, Med -> 1-Start with this to stabilize stagger bar
Sen, Rav, Sen -> 6-Protection against feral links while filing stagger bar
Med, Sen, Med -> 5-Healing
Rav, Rav, Med -> 3-Cure while filling stagger bar
You will have to change paradigms A LOT, you have to be on your toes, and see the attack patterns to know when to attack.
Good Luck
