To all the players who are supporting the '' revert rengar '' thing
i was a rengar main in s6 before his rework i even have a lvl 7 badge with him and a skin ( 120k mastery or so enough to understand what is rengar )
you're asking for a rengar revert yet you tend to forget the insta deaths after you see the red mark above you .. Crit thunder-cat was absolutely broken and not fun to play against especially if you're an adc , but he was fun to play with but yet still at the same time he was a toxic champion either useless against some team comps or unfun to play against.
i stopped playing him after the rework because the rework sucked , but that doesn't mean they should revert him because old rengar was like
fun to play with and not fun to play against.
They should just
him and hope it doesn't fail again , and oh riot atleast admit that you made mistake and you failed there is nothing wrong in admitting mistakes we're humans after all making mistakes for us is only natural you failed 
It's not like i am happy with rengar's current state , as someone who used to play alot this champion i can completely agree that reverting him won't fix it , before the rework people kept asking for a rengar rework because he was broken and toxic champion and now you're asking for a revert ?
