''YI IS OP AND A PROBLEM IN DECENT ELO''

True, one stun and Yi dies.

"But muh can't be slowed" In decent ELO, theres more to CC then slows. There are stuns, roots, knockups, killing him, and so much more.

people will allways complain about champs they don't want to bother to learn how to counter... Shivana is easier to shutdown in teamfights than yi (no untargetability, no slow imunity...), but because teamfight is forbidden in ranked, shitstorm happens
