Lee Sin is an example of what it takes for a melee to be good in this game
Arguably the most broken champion in the game is melee and it takes an overloaded ass kit that's completely overturned with everything, numbers, versatility and just random stuff. What does that say about this game that has become so damn anti melee? If that's what it takes for melee to be consistently good, there's a problem.
All great champs, all melee, not assassins.
an assassin since she isn't you know, also there is mundo who is always in a weird kind of in the meta never being completely useless but he is also melee
