I quite like the idea of the Luck stat there. Don't mind me as I steal it.

The stats I'd go for would probably look more like this:
  • Power - Increases damage and healing
  • Dexterity - Increases critical rate
  • Vitality - Increases maximum HP
  • Mind - Increases maximum MP
  • Agility - Decreases GCD cast/recast time
  • Luck - Increases proc rate and critical damage

That said, if I really had my way, pretty much most jobs would make use of MP in some form, yes that would include non-magic jobs like WAR, DRG, MNK, etc., just so MND would be beneficial to them in some way and possibly affect their rotation in a way that just simply upping damage doesn't achieve.

Imagine for example that Inner Release on WAR had a short cooldown, but consumed all your MP, and however much MP you spent would determine the amount of IR stacks. Let's also assume that doing the rotation also gave enough MP to let you use 3 IR stacks every 60s like now. Suddenly MND becomes a "I can Fell Cleave even MORE" stat, which gives a meaningful change to its rotation since that can also affect things like the Infuriate cooldown and when you might want to burst.
