Even the LCS Casters are visibly disgusted with Ryze

And their job isn't to bring up balance or talk about it. In fact, I'd go as far as saying they're supposed to remain neutral when it comes to expressing any sort of suggestion that a champion is way too strong. Even the analyst desk after Gravity vs Liquid basically said "they can't imagine him not being nerfed next patch despite nothing currently on PBE for him." But there's just nothing they can say but this: he's literally that broken atm

Let me tell you something: this is the most broken thing I've seen since release Zyra. She was hotfixed. He's just AS BAD. You don't wait until the next patch to change something like this, even if it's just a few days away. The fact that something like this can exist in a normal SR game, it ruins peoples playing experience. It ruins the game for the person who has to lane vs him as well as the enemy team of him. And don't say "just ban him hurrrr" because not everyone plays ranked or draft, many people play team builder, blind and even ARAM. And there are still people in ranked who aren't informed as most and let him go, making your ranked game feel miserable because Ryze somehow got through.

This NEEDS TO BE HOTFIXED. How it's avoided that so far is beyond me. Even your casters, the people who are supposed to be the least bias, can't stomach this and visibly show their disgust for this.
