I would like to point out that there is a difference between knowledge and practical experience. like for example Goku is a moron when it comes to being intellectual, hell he didn't even know what girls were when he first met Bulma, but he is a genius when it comes fighting, Vladimir doesn't know as much as the others but he can adapt and understand what the effects of situation can be. It's really just a question of whether or not knowledge or practicality matter most when it comes to leadership. But I don't mind if Kane becomes leader
