Every meta where Lee Sin sucks in has turned out to be even more terrible.
If you think about it, it's true:
In season 4, Lee Sin was good and most of the time you could play alot of champs. In season 5, Lee Sin was good even in the Cinderhulk meta, until first Sated Devourer then Juggernauts, and he fell off the map. In season 6, Lee Sin was never good, and neither was the jungle meta going from Mundo/Volibear only to Yi/Shyvana/Xin only to Nidalee/Graves/Kindred only.
Lee Sin is like a barometer. If he sucks, then that likely means even more OP champs are around or that the jungle has become too unforgiving for even him.
