What about changing the damage ratio of the -RA and -GA spells?
If I remember correctly Fira deals 110% the damage of Fire and Firaga deals 125% the damage from Fire. Fire could be weakened while Fira and Firaga strenghtened (If there's 0 MP at the beginning).
Just saying, I'm still not sure myself as it seems N'mou Black Mage Geomancy, equipped with something Robe dealing over 600 damage with Firaga seems kinda broken.
