Playing an immobile caster against Mordekaiser devolves into 'rush QSS or be removed from the game'
How did this even get released?
Even if he lands nothing, the positioning and size of the arena prevents him from being kited; once you're backed into the wall, there's nowhere you can move without him getting on top of you. He doesn't even need to land abilities, he can just run you down with his passive and auto you to death.
This is not healthy game design.
