I don't know... It sounds like if you are just moving all stats away from armor and rolling them onto materia, you're not really changing anything. Instead of new armor and weapons every level, we would need new materia at every level. And then what's the point of having any armor or weapons other than aesthetics? Attribute gains attached to the PC upon level up seems more geared toward a single-job type game, in which the PC cannot change jobs/classes. Otherwise I could see how changing job/classes would work toward improving particular stats at level up; this reminds me very much of FF6 where you would assign particular espers to your character upon level up in order to obtain the "perfect" build. It was honestly a nightmare to try and micro manage a character to that extent, so I can't see how this type of system would be an improvement over what we have already.
