I think he needs commanding skills and mental fortitude. I expected him to aim to be a good leader, not a good warrior. Well, if it works, I have nothing to say.
I admit the last part is funny and yeah I believe he won't be able to become a truly strong warrior @HuevoPodrido is right, hes better of honing his commanding and leadership skills. Like what right piece should he move at the right time and place. (im no saying theyre just chess pieces, its just an example)
