I feel like Satou is a "deal with it when you need it" sort of person. True, that Coaching is probably not necessary to max level, but it was a skill needed in the moment. You see him do something like that when resistances come up that he needs in the moment.

That's part of the reason Golden Wild Boar King said Satou felt so "artificial" because he doesn't have a skill-set for someone that worked his way all the way to that level or even a level of hero. He's got like max points in stiching, singing, coaching, and swordsmanship but no real interpersonal combat skills.

Basically, Satou fights gets skills, maxes the skills, and overwhelms. It's not about building a Hero character with balanced skill points, its about fighting something that works and exploiting it.
