One important thing to note about brittle.
Say it increases CC by 1 second. They couldve just given him a 1 second stun instead of Brittle. In which case it could be combod into a morg Q.
So before people are like "TENACITY PLEASE" just take this into account.
(I know that there are some differences like ease to land other CC, difference in types of hard CC, as well as his ult apllies many. But this is just a reminder)
