Mordekaiser's ult is a point and click death sentence
90% of the roster can't 1v1 him unless he's extremely behind. The ult lasts for too long, which makes it extremely hard to stall.
I have no idea who the fuck at Indie Company™ though an ultimate with such little counterplay belonged in this game. It is disgusting.
The fact that he has 53% in the patch he got his rework speaks for itself
cancels his ult
