I always kinda liked the classes for their customizable "side" stuff; it always felt like you could make ACFs that would replace a Limit Dragoon's Dragon companion easily.

I also liked the elegance of how said side customizability was quite versatile.

The one problem I'm having with your fix is that you removed the part that prevented you from, you know, bashing your head against the wall a couple times to fill up your Break pool. Plus, I prefer a smaller number of levels, but that's just me.
