"X champion beat me, they must be OP."
If you find yourself writing a post because of that reason, stop. This section of the boards has more than enough of those.
If you genuinely believe that a champion is overpowered and is in need of a nerf, go play that champion a few times and determine the area of their kit that is too strong, how to go about giving that part of their kit a nerf without ruining the rest of said champion, and present it in a manner that even a main of that champion could agree with.
