IF you could nerf one champion right now...

I actually am not answering the question, more responding to an answer I saw when I was reading PBE stuff. The question was posed by someone to Draggles, his response was... wait for it... ? It's about 3/4 of the way down the page:

I can't decide yet if he was just trying to be funny, or be serious. I can't imagine a meta that we would have to be in for him to be an actual answer to this question.
