I counter that proposal.
Not everyone is going to attack you in a fit of rage because of repeated fireballs. For example, what if they have A, S, or even K groove themselves. With A-Groove, a leap-in with a timed activation and a decent custom can put you in a most uncomfortable position if they decide to jump in, provided the bar, of course. But as far as turtles, the ones in S and K groove have decent counterability. Think about it. Multi-fireballing someone who can either multi-dodge or Just-Defend accurately can constantly be a real pain in the ass. The dodging will just avoid the damage. The JD’ing will just feed their greedy asses. Juiced super bar and energy recovery? A nasty combination, indeed. I know. I have annoyed a lot of people doing that shit on console and in the arcades. Really can tax on a person’s patience/strategy.
With that said, you may end up being that person attacking in a fit of rage.
Not to be totally offensive, but I thought that point needed to be thrown out there.
