PBE Rengar Is Too Strong

PBE Rengar does way too much damage right now to make it to the live servers. I'm seeing him get insanely fed, either on my team or the enemy team every single game. While PBE isn't the best indicator since it doesn't have players of equal skill levels playing together, seeing Rengar get fed every single game without fail is a bit concerning in my eyes. I think he should remain on the PBE right now and maybe strip a bit of power from him. Right now, he's back to the exact same champion people were constantly banning when he was floating at around a 53-55% win rate. It would be stupid to see him hit live like this only to be nerfed a few patches later back to a similar power level then where he's at now on live. It feels like a waste of time for everyone involved.
