You really like OP servant lol. Passive stars and cCrit with his already good star gen with be very OP if not broken. Jo probably: But Not OP Enough!

He is more fit for Saver class but he can also be Ruler class because of reason you stated. And ruler class doesn't need to be saint, look at Sherlock, QSH, Quetz and Artoria Ruler...
