"Lee DOESNT fall off. He simply doesnt burst people for as much as he does in earlygame if he builds bruiser"
Yeah isn't that what FALLING OFF means? He doesn't do the same amount of damage, which is why he's weaker late game.
"His late game isnt terrible. He either build tank and enjoys great utility and top-notch mobility, or builds glass cannon and becomes an assassin that kills you in one combo"
If he goes full tank then he is for the most part useless. Only good thing about him becomes is his kick and not many know how to properly utilize his kick late game. Also when that kick is on CD he is literally almost useless. If he goes full damage then he will get easily focused and 1 shot, which is why you never see any pro/ good lee player do this.
"Yeah, and then nothing happens. He doesnt get punished by his mistakes, neither he loses mana or much time. And his gank isnt ''done'' either, because even without his 0 risk high reward Q he still has better ganks that many dedicated junglers. He has ward hopping and amongst the game's highest MS. He can simply walk in, W them for a slow and have Q ready by the end of the gank."
Showing up to a lane and failing a gank is very bad for a jungler. I'm assuming you're either low elo, or don't play jungle. Here's why this is bad. One it tells the enemy exactly where he is for nothing in return. This gives the other lanes the ability to do whatever they want without fear. Two you are wasting quite a bit of time that you could of used to farm. The more you waste time the higher level the other jungler is.
"Are you serious? Early junglers are always the best. Cinderhulk? Counterjungle the Sej/Amumu or simply get lanes rollin while they are still (slowly) cleaning. Devourer? Get lanes fed while the Devourer farms. Early junglers were/are oppresive for something: they could clear and gank at such speeds that they could win the game before the enemy champion even started ganking."
This is your opinion, not fact. There are Devour junglers such as Shyvana and Xin who are pretty good early and with the Devour they become god tier late. Also you snowballing lanes isn't always guaranteed. As soon as you get to Mid/late champions such as Kayle, Xin, Shyv, etc will all become way more useful than you. Also counterjungling is much harder this season than before. Losing a buff isn't that big of a deal now and warding isn't hard. A good jungler would simply buy a green and pink ward and when they see Lee in their jungle they call over their lanes for a free kill.
"Please inform yourself before embarrasing yourself."
Man you obviously don't play Lee Sin and are probably a low elo player. Stop being cocky when you know nothing
