When did Rengar become the target of the hate train?

Maybe it is just me but when I see threads complaining about Rengar all I see is whining. That is it. No constructive posts. No "this is his weakness and here is how you handle it." Just threads whining that 'there is literally nothing you can do against a Rengar" or "he has zero counterplay!" Both statements are exaggerations and annoying. Rengar has two states. A good Rengar player that gets fed and requires you to position and react properly to beat and if you don't you deserve to lose or your everyday player that just feeds you. I have seen a lot more feeding Rengars than I have good ones.
