Please buff Mordekaiser

Riot, I love Mordekaiser, and he's probably one of my favorite champs at the moment, but goddamn he is so useless sometimes. I've had some ideas of how Morde can be buffed a little so that he's still fun to play as, but also not extremely useless, especially in a 1v1, or even a team fight
So, Mordekaiser has absolutely no stuns, slows, snares, etc. I think that he should. When he's chasing someone down, there's no way he's gonna be able to catch up, unless he uses flash and E and ult perhaps. I really wish that would change. I think that at least one of his abilities should have some kind of movement debuff added to it, for example, his E would slow enemies by at least a small amount when he hits them. If not his E, at least his ult, or SOMETHING. But Mordekaiser definitely needs one of his abilities to have a movement impairment added to it, so he isn't totally useless except in teamfights
And even if that isn't acceptable, I think his passive should have something like Annie's, where every certain amount of abilities used on enemies should stun. I feel like something like that would work out nicely for Morde
So Riot, if you do see this, please take this into consideration. I love Mordekaiser and I love playing as him, but it's irritating basically just having to poke enemies from the start and then teamfight for the rest of the game to do anything effectively. I need to be able to chase and kill, especially in a 1v1. If the enemy starts to run, that's the end of it. They got away, and there's no way I'll be able to get them because for one, I'm immobile, and two, I can't impair movement
