@oculunus Honestly I don't really see it as a cheat. What makes is maybe cheap, is that he is an heir to a territory, which is what makes that ability potentially strong. If he was just normal dude mcguy running a Popsicle stand, he would have to develop extraordinary leadership skills to be able to have people, especially talented people, to follow him. Because he's already set to inherit, people already are treating him as a future/leader-to be, so his leadership skills are already on a fast track.
A cheat would be to kill a slime and then suddenly gain enough magic to lift a volcano or throw cities at other cities. That raw strength is a cheat. Being able to help others reach their potential is the ideal skill set of a manager, not the Yuusha whose going to beat the evil Maou for the Heavyweight Championship belt at SummerSlam live at the demon castle.
