How do you manage to rework a champ to stop them from one shotting and somehow make it worse???

You gave Rengar a guaranteed crit and a cc immunity. What happened to all the pathetic Rengar players saying his only counter was no escape and grouping as if that ever mattered? Honestly how the fuck can you even defend this champion anymore. Same with Yasuo. I don't even want to think about how bullshit his rework is going to be. Next thing you know Yasuo will have bonus crit damage that heals him. This season is already a bigger failure than six and it's been 2 months.
