Let's be honest here: who actually hates playing against Lee Sin?
I realize he has an overloaded kit with many bells and whistles attached, but Lee Sins I play against rarely use his kit to his full potential. He's a strong early game ganker? Guess what, so are
. Lee Sin's kit is powerful if you know exactly when to Q, when to ward jump; most people (myself included) don't. The junglers I listed are usually far more annoying to play against. And, unlike the devourer junglers, Lee Sin falls heavily lategame. Compared to
, who is annoying as f@#$ to deal with in lane AND has a strong mid/lategame, Lee just feels much easier to play against.
Disclaimer: I do not main Lee Sin. Outside of the free week, I haven't played him in the last three months.
, basically any tanky jungler who has slow clears cannot function in a meta where Lee Sin is dominantly played, because he is absolutely unpunished for just walking into your jungle, throwing a Q at your red to check it, and if you're there, jumping over the wall and dueling you. If you turn it around, he ward jumps out. If you don't, he kills you, sets you behind, starts snowballing, and THEN ward jumps out so that your lanes can't come help you.

as well but nobody plays him anymore.
