if rengar got this small appropriate nerf, his winrate would drop to below 10%
i feel rengar should be changed to get a new passive to where all ranged champions on the enemy team are forced to spend all gold after 3000 on a randuins
basically the way it works is. if rengar is on the enemy team, and you are a ranged champion, then the game forces you to spend gold after your first 3000 on a randuins. and once the randuins is done, you can buy any items you want afterwards
if rengar got this "nerf" (basically a new passive to force the enemy teams ranged champs to buy the strongest rengar counter item) his winrate would probably go to below 10% without even needing to nerf rengars actual damage
