cho gath op?

hey guys, im just asking why people are thinking cho is op, or even super good for that matter. every time I face a cho mid I just butt stomp them with champs I play all the time (notably fizz and yasuo). these champs are apparently e z matchups for a cho. and I know that there are gonna be a ton of spam comments saying that the cho'gaths I faced just suck, and that may be the case, but he is pretty easy to play as far as I understand. I don't play cho but on streams I see him played a decent amount and he seems pretty straightforward. and I know he is one of the only champs in the game left with a silence but if you would notice it took a lot more to nerf than just that one mechanic on champs like kass. looking out for some other opinions from people who hopefully know a lot more about him than me who just saw some streams. ty toodles :)
