Could we weaken yas late game and buff him early?

Sick of wondering if the mid yasuo on my team gonna go 20/0 or 0/20

I think reducing some of his scaling whilst also reducing his CDs would do the trick, maybe add higher base damage to his q but make is scale way less?

I'm just throwing ideas, the main problem with this champ imho is that he is too much of the flip of a coin He's either OP or useless
