Why is Sett A Thing

I'm honestly not too sure what Riot was thinking when the created Sett. The champion is so overloaded with his kit and needs unbelievably tuned. A stun, true damage, I think his ult suppresses, and a shield for his entire HP bar from a non ultimate ability. It's just ridiculous. Anyone can look at this and know that he's unbalanced so I'm not sure what the design team was thinking, or if they were at all.
