and he certainly is strong, but id just like to point out that, according to Champion.gg,
all have higher winrates than Mordekaiser. I can honestly say ive only ever seen calls for nerfs for maybe 3 or 4 of these listed champs. Hell he has only 0.1% over Ahri, who is one of the most low-key broken champions in the game, but barely anyone complains about her.
Just a little perspective for you guys. He loses to any champ with half decent poke as long as you're not dumb enough to get caught in his E which has a 24 second cool-down at rank 1, and wont realistically have less than a 14 second cool-down by the tail end of the laning phase.
