Why is Yasuos Ult on such a low CD?

Im so fucking tired of this guy being able to ult every 45 seconds basically... theres no reason for it... really...

hes already a hyper carry outside pro play... he scales way too hard way to fast for alot of games, and being resourceless it just makes no fucking sense that hes given a suppress that often... atleast WWs suppress only hits 1 person and does laughable damage.... yasuo can suppress up to a whole team and still does relatively high damage....

get out of here with this bullshit riot
