Rengar has to be the worst champion to experience in solo queue. Please rework him.
Title.
Your support gives him first blood at level 1 and then your jungle
feeds him; suddenly you see what is known as the "Rengar Tax" where
kills a champion every ~90 seconds for free just because he was fed early. No amount of CC, burst, anything will keep him in check - he will go around with 60 Lethality and 5000 AD and take turns one-shotting while you wonder how your bot lost for the 7th game in a row. Fast forward to 30 minutes and there are 0 wards on the map, Gragas is level 12 while Rengar is 17 and completely disabling your entire team from accomplishing anything.
You will ban Rengar from now on after what you have experienced. You will come on the forums and type this out. Suddenly, during the last paragraph of the post you'll realize that over half of the people browsing these forums are either
mains or playing support and are therefore just as helpless against him snowballing from bot lane as you are from top. Neither Riot nor anyone mercilessly performing terrible invades and feeding him will read this. Nobody here is your target audience. This post will be ganked by Rengar. You will be ganked by Rengar.
