The real problem in league
Riot has no procedural integrity in their balance decisions. All they have are some shitty subjective theories (which is ok since game design is an art not a science), but its a problem when they are trying to apply the artistic principals to game BALANCE which IS a science and that is why they fail.
They are making changes to yi based on "feelsgoodman" ideology rather than the scientific fact that he was fairly balanced before sated meta mandated his nerfs. Its scientific fact that his nerfs should be reverted now that sated is no longer meta.
Now, its possible that rageblade somehow becomes mandatory on him as well. But not all of his nerfs addressed the phantom hit. Some nerfs affected his ability to clear minion waves which is far out of bounds. However, this isnt going to be detected or addressed because theres no science in the decisions..only feels..
