The Problem Isnt Necasserily Lee Is OP
It is that he has been on the top of the Jungle for so long and that he has been one of only three viable champions every patch for such a long time that people are sick of seeing him. Great, he can do everything and doesnt fail at anything, but doesnt exceed at anything except mobility. That sounds like a champion where there is no point in not picking him since he has so little weaknesses that it eliminates the hard part of playing a new champion and that is learning their weaknesses, something that falls down to only dont get rooted, stunned, or knocked up as Lee Sin. This is NOT necasserily OP, its just I am so tired of seeing him every patch as a big dog in the Jungle while 12 others are left in the dust. There is usually 2-3 that get to hang out with Lee as the always pick in the Jungle each patch, but they leave after 2-4 patches. Lee remains however and seeing him every other game all the time is getting incredibly old.
