I don't understand the logic regarding Lee Sin

Lee Sin is known to have an above average popularity but a below average win rate. This theoretical shows that he's difficult to play, but is extremely rewarding when played well. This means that the only people that should have problems with him is the LCS.

Now people are saying that Lee Sin isn't being nerfed because Rito only cares about the Pros. But if he's really only a problem for the Pros, aren't the people complaining the one asking for his balance to be centered around the LCS?

(not saying the nerfs aren't justified, but I don't understand this logic)
