I think it would be a cool idea if you got strong enough you could build up more ki bars, like lets say you reach ssj, you could have like 3 or more ki bars and make ssj just barely... dig up some of your ki, so when you have maybe like 7 bars it won't be too much of a problem and you can sustain fighting longer
Oh yea... you people that are thinking of flaming me, f*** you, and suck my d***
