"Hmm Shaco been problematic since rework"
LETS JUST TAKE EVERYTHING OFF HIS SKILLS INSTEAD OF JUST REVERTING IT!
I don't think the dedicated Shaco players would mind his kit being reverted 6 months if it meant he didn't get nerfed every single patch.
His play rate would drop. His ban rate would drop. His win-rate would probably drop a little bit.
He would go back to the plane of non-existence and you can leave him alone.
You've put more work into balancing reworked Shaco than you ever did with reworked Kog'maw, but you ended up reverting him.
