I just wished they did materia like jewels in monster hunter games.
10+ of skill = active passive skill.
Lets say 10+ TP quick regen
= 5% faster regen
20+ TP quick regen materia points= 10% faster regen
Because honestly this materia thing is getting more lame each patch and is almost irrelevant unless u r trying to reach some kind of coil requirement.
Other than that it has no other uses that retain its value outside of coil.
