I agree with 14 spells being way to few for magic class. They realy copied this from other MMOS where the mage classes have the same amount of abilities like any other class. The problem is here it doesnt suit Final Fantasy that much.
Giving Conjurer Wind, Earth and Water and giving THM Fire, Lightning and Ice is ok. But restricting mages so much by basicly taking away so many spells makes them just like any DoW class. The only diffrence left is that DoM use MP and DoW use TP.
