Regarding Mordekaiser.

The only thing that really gets on people nerves when playing against him is his no counter, point and click ulti. Not only, is it a 1v1, he becomes stronger than you, and some champs like kat and I believe heimer lose their dmg (kat daggers heimer turrets). I can't kite forever, and I simply can't sacrifice some of my items for qss or zhonyas, and it isn't easy to zhonyas during the cast time, Especially in teamfights. So, I have a few ideas with which you can make it more "fun" to play against, I guess. Maybe he needs to land his e/passive first before he can ulti, that way you can juke his e and outplay him, rather than hope he doesn't choose you, and, as compensation, his e gets a reset (so he isnt useless) and u cannot cancel it afterward. Or make it so that he can only ult when the enemy is under/over a certain amount/% of health. Maybe if while in the ulti, if mord drops below a certain amount/% relative to the target it isn't cancelled. (so if they are both at the same amount of hp it isn't cancelled)

Let me know if I'm just salty because I play kat/jinx most of the time and mordekaiser usually shits on me. Or if these are reasonable suggestions.
