The real problem with shaco:

Is that most of his damage comes from artificial scaling items like and the thunderlords keystone. The thing is he is one of the best users of artificial scaling because his kit was made for it. Rito then nerfed his raw kit damage, making him even more reliant on artificial scaling. Unfortunately, he still has extremely low counterplay due to the lack of anti stealth mechanics. So I would say the shaco rework is a complete failure.
