The champion most in need of a rework

Just wondering what your guys thoughts was on this. I don't nessicarily mean that the champion is too overpowered or underpowered. I just mean the ones that are broken overall. I personally would like to see a xin zhao rework, while I do think some champs that are easy to play should be left for new players I don't thin xin zhao is one of them. I've played a lot of xin zhao, he was the first champion I played that I could do well with, but his kit is completely broken, he doesn't have much counter play unless you pre-emptivly flash away from him, and his damage is crazy. I would like to see him get a kit that takes a little more then pressing e-w-q, right clicking, occasionally pressing r but getting a penta kill.
