There is a simple reason as to why riot isn't going to revert mordekaiser changes

They aren't going to revert it because that goes against the rules of champion and rework design. You don't rework something on live, see that it's horribly imbalanced or just plain wrong, and then revert it. You make it work. But until I see the details of the marksman update, I doubt it very much that they can

Morde mains endgoal is to see him Reworked to a HEALTHY and BALANCED. State

We ask for a revert just so we can actually enjoy playing a champion to have fun again

For a few months atleast
