Unpopular Opinion: Lee Sin is not hard to play AT ALL, doesn't fall off, why new champs overloaded
No part of his kit is difficult. His Q is a MASSIVE hitbox long range massive dmg execution on a low cooldown with a low energy cost. Oh and it also gives true sight cuz why not? His W is a self + teammate shield that can also just be cast on himself that is also a fucking second dash that can be used on a ward for even more bullshit slipperiness. His E is a MS slow (and also something else that I don't know because why not overload the literal fuck out of him some more) that is ALSO an ability that gives him true sight, because, again, why not overload the fuck out of him. His ult is a root/knock up/knock back that scales on missing HP as well (because he needs two of everything in his kit cuz GOTTA BE OVERLOADED!!!!!). Then to top it all off he's the original two passive champ. Extra attack speed AND energy regain.
This champion doesn't take skill, and he certainly doesn't fall off as the massive amounts of CC will never fall off. He's the reason that champions now are so overloaded with 80 abilities each.
all see jungle play, and so he looks pretty hard relatively.
