Suggestion for FS heroes

Hey folks. I noticed EP heroes have different levels of ep for their different skills, couldn't the same principle be applied to fighting styles? By that I don't mean you need blocks in Taekuwndo and Karate respectively. I mean like, hand to hand, as opposed to fire arms training, or nun chuck, throwing stars, swords, or any other fighting style really. Perhaps the first three blocks could even cover general training, then every block after that would be put towards a specialty. That way it's a little cheaper to manage.

Or just leave it as is. It works this way too. This is just something that occurred to me.

As an all encompassing stat its simpler, with the rules we already have in place this would make new users heads explode, I dont think its a very good idea
