Rengar is pretty much unstoppable

Another post about Rengar being far too strong. Perhaps something should be done. Anyways Just played a game against Rengar, and they had 27/6/4 where they had 41 total kills. Granted 31- ish kills isn't out of the norm, but we could be firing on him and he could sweep our entire team if we weren't already next to the inhibitors as we had no chance to even step out. I had to constantly keep check and there wasn't a lot to do. I kid you not I watched Rengar dive in between two towers, take fire from both, and 1-4(too fast to tell) shot both Ezreal and Talon, not tank characters but still. With a attk speed lifesteal xin zhao Build I was a squishy and even when he had little to no health I had trouble even when popping my ult. Absolutely stupid that Rengar should be that strong. I've seen these posted everywhere and one posted 2 months ago. I don't see all that much of Rengar but with what happened last game, I hope he's nerfed and I never see him again.
