Morde is beyond Broken

So, I was playing a Ranked game earlier and I forgot to ban Mordekaiser. And so I was like no problem. (I had said this because i had fought a Mordekaiser earlier and had beat him heavily). But then out of no-where the Mordekaiser was literally just hitting me 3 times and I die. Not even popping his ultimate just auto attacking me.

I couldn't kite him, my team couldn't even cc him down. There was also one point in the game where our Leblanc and Evelynn went for the kill on Mordekaiser then he was at about 300-400 Hp. Mordekaiser just turnt around and bopped them a few times and they both died instantly.

CC isn't even a counter play to him, Mordekaiser has a 76% win rate if the game ends before 25 minutes. Thats fucking utter bullshit honestly, please nerf him.
