Riot seems to be very respectful against disabled people

Hmm, I went and read his scaling again as you suggested. They ARE higher than I thought. But I still think they are not really at the point of unacceptable. I still think its not hard scaling. so we can just forget about this, since it would require pulling out alot other numbers from several junglers to justify each of our claims. (When I said he has no hard scaling, I mean a lot of his late game scaling comes from his utility, since most Lee Sin build 1-2 AD items only unless they are snowballing the game. So I agree with out on Lee being a asset to the team even if he is not fed.)

When I said the community like Lee Sin, yes you are correct mostly are those that religiously played him for years. And I ain't one of them. And I still think I generally like lee sin's way of play. (There was a time when he was stupid strong in S2 where I really want him to be deleted, but that time has passed.)

I think balancing Lee Sin is touchy not only because the community likes it. The LCS pros "like" him, too. Well I meant not actually like, but almost all of them know how to play Lee Sin. So basically Lee Sin is like the one jungler everyone needs to know, which indicate that he has a high hidden influence on the meta of junlgers. (He actually have a lot less now compare to S2-S4, since the popularity has dropped a bit.) By nerf/changing his kit and making him over all weaker, some other junglers that is not played due to being kept down by Lee Sin might all pop up at the same time. And that MIGHT completely reshape the meta instantly. Or it might not. However, there IS that possibility.

And completely reshaping a jungle meta have a cascading effect on all the other lanes, since jungler have huge influence on early game, and early game would decide the rest of the game. Granted this is only the extreme case. I think Riot would rather avoid this. Lee Sin probably won't receive any major changes unless there is a HUGE problem on the pro level.
