Make physical levels rule HP, MP and TP. Separating HP from Vit and MP from MND would be awesome seeing allotment will be at classes now. Having a way to raise HP, MP and, occasionally, TP would bering a brand new life to physical levels.

Like allowing to add up to 1000 at one of these attributes if you put everything in one or splitting this 1000 points the way the player feel like doing would be an awesome way of customization.
