To be honest I think they will be moving the elemental nuke spells from CNJ to THM for the following reason: Intelligence Materia can be equipped to a THM one-handed and two-handed weapons but not any CNJ weapons. Based on the new stats, INT raises the magic potency which nuking spells use.

I was really hoping that CNJ gets BLM but looks like I will be leveling my THM to 50. I'm not much of a WHM kinda mage.
