It's true, access to tanky damage is now really easy, but at the same time I think Lee can afford to have tremendous tankiness and damage on top of top-tier mobility, again because he'd be needing all of those tools to make up for his lack of reliable sight.

While you're right that solo queue is notoriously disorganized, I think that would just be a reason to try to fix that a bit, instead of just accepting it as is. Champions are meant to teach players new ways to play the game, as well as teach them how to play the game better using common mechanics, and in this case Lee Sin would be the perfect champion for teaching the importance of warding and vision control.
