Is Chauster the Cockiest Player?

This video's actually 4 days old, but I've been a bit busy studying so I haven't had much time to browse around.

As a disclaimer, I've followed Chauster from when he used to main Ezreal and was very impressed by his gameplay.

However, he's also possibly the cockiest player in League of Legends I've ever seen! Perhaps it's rightly so, but wow he just emits confidence/cockiness from every pore...

"You go against them, and you outplay them, and you kill them consistently, and you beat them consistently, and then you ask who else is left? There's no one."

"When I started winning 10~20 games in a row I realized there's no one really better out there."

I'm on top of the world!
