Maybe this bar should start growing when you get under 10 hp? You loose PL then, soo maybe the loosed PL would fill up the specil attack bar!! I love liit breaks, I LOVE Final Fantasy, but I think ESF needs something original like my idea! When you are low at health you loose PL, soo just make that the loosed PL would slowly fill up the "meteo attack"(how you named it) bar!!! Then people who would like to use super attack would need to wait till they loose some PL while being low at health^^!!!
EDIT:
I voted for this attack, but I think my idea of charging it is the best and most balanced! Not many people like to loose PL, soo if they need to loose PL to charge this attack: 1# they will stop killing themselves after they are low at health, 2# they will not wait specially for this attack! Also the bar should fill up slowly, but stay even after death! untill you chage it and use the super duper ultra attack
