Make Each Class Use Each Stat

[Reynhart]

That does not even make sense and is actually completely impossible without changing how the game works completely. >_>

Actually, it does.
Nobody cares about VIT and PIE, so you jsut have to set HP and MP values for each job/level.
And apart from that, you could just fuse STR and DEX into Attack, use Magic Attack for INT, and Healing Potency for MND.

And again, pretty much all stats just increase damage, no need to have tons of them...
