Bringing back his old passive. It was incremental to his identity back then that he had to spend health to deal damage. And get that damage as a shield to take hits then move his new passive to the W slot at a lower circle. Because lets be real here, it just feels way to much like an AoE darius passive. His Q should be the 3 autos again. It had counterplay in the sense it needs to wind up first before the damage. The Q right nust feels real wonky. The W isn't any better either. The passive would be better there. You can give it counterplay by:

Making it so that he can only use it at max shield strength. That would make it fair since morde would have to deal more than he can take to activate an AoE soul/metal shrapnel field

Maintaining it would cost health over time but the damage it deals gains back shield strength. And destroying all of the iron man shield ends the duration.

There should also be the option of ending it early to turn the shield strength into a heal. It would make it into a situational skill that has high payout if used right.

Let's all admit it. The rework fucked up. He's just AP darius with a camille ult. His story and viusals might be shit tons better but his gameplay is so boring. Its uninspired. This petition is to give him the 'Pantheon Treatment', keeping the flow of his old skills and gameplay but modernizing it. My suggestions would be:4. His E is like darius E but worse in the sense that its hitbox is bad. Its just a reskinned carbon copy of the darius hook. You could change it up by having him slam to ground to make a slow field. You coud reuse the animation of Q to crack open a slowing portal to the death realm. You could reskin vel'koz's W there when it hits. Just a suggestion.5. His ult is an unrewarding Camille ult. It doesnt help with anything and a QSS would pretty much counter it on a 2 minute down time. 10% doesnt even feel like anything and overall feels clunkier than ever. His old ult would be better here even if theres no dragon. If you cant, why not instead of giving 10% stats, how bout sapping the targets health instead? It works thematically too cuz the death realm saps away their life till their just puppets. And helps morde out more cuz its a heal and maybe even a bit of iron man shield. And the reward for killing them in the death realm should be the ghost. It was a unique mechanic he had and was also the most iconic thing.Please riot. Listen to your community. Not even pros play him cuz he's so easy to punish. And everyone, especially 98% of the r/mordekaisermains community hate how boring and generic you made him. And finally, please bring back the heavy metal music references in his abilities.
