New Mordekaiser and Juggernauts

I think the new mordekaiser is waaaaaay too op first of all whatever you build on him is op and you can go any lane as him and you will crush basically but bot is the best. Once he gets his q to fifth rank or his first item complete then you dont stand a chance, his q with kill you, i got a penta as him my first game and i was like this champ is digusting i might sound like a complaining kid but im srs there is NO counter for him, i mean 1 champion i found to be ok against him is yorick but no one really plays him. When people ask you to nerf someone try to plz dont nerf the less op people or dont change anyone to make then more op then they are already like the new fiora is ridic and in bronze or normals you cant win against these champions.
