From a Diamond 4 68% W/R Rengar OTP, DO NOT buff Rengar!
Rengar is a really fragile champion in terms of balance. I would argue that he's healthy at 48%-49% winrate, and right now he is at 50.35%! Then you go and lower his ultimate cooldown early game which is an insane buff in soloQ as you can spam your ultimate more which usually nets a free kill.
But it doesn't stop here, ON TOP OF THAT you go and buff Rengar's ultimate duration at rank 2 and 3. This is in particular completely insane in competitive. Have you forgotten "The thrill of the Zone"? When Rengar was reworked his ultimate warned from a larger distance but alsothe duration was very long, which needed to get nerfed as it wasn't used to "hunt targets" but to "zone enemy teams from objectives". Please stop this madness.
HE DOES NOT NEED BUFFS!
