[@Baklava][@Letter Bee][@GreenGoat][@January] I'm not sure how I'll explain this, but I'll try giving an example.

Fire Manipulation would be their base magic then stats would be how you'd describe what you can do with your ability. The letter grade would just tell everyone else how good are you in a certain aspect of your magic. If I'd use Rhian as an example, maybe I give her the sub-abilities of Control or Size Scaling.

This is just me messing with ideas and doesn't mean that the change in the system is something definite. Personally, I enjoy outplaying your opponents with wit and creativity that just going with a mentality of "My Stats > Your Stats."

Instead of being used for comparing character's capabilities, it would serve as a marker for yourself to know how good you are at something. Then eventually, we can add unto these sub-abilities to make one's magic more unique or diverse?
