I'll be completely honest with you, the movement speed bump is really all that Mordekaiser needs, if he even needs that. I could also potentially see W carrying a very slight speed bump for Mordekaiser, not a slow to the enemy, but a speed increase for him. Mordekaiser is one of those champions like Olaf that sits there saying "Please try to all in me so I can delete you from the rift." Giving him super strong chase and sticking power would make him exceedingly toxic to the game.

Rylai's was already suggested, which is largely sufficient to deal with his mobility problems, if you need more pick up furor or alacrity and he'll be completely fine.

I'd venture to say that in his current state he's rather balanced as a top laner and building in a mix of largely offensive and defensive stats makes him quite the force to be reckoned with. Sure you get kited by ADCs, which you should for the damage you do, you also get out dueled by some assassins, which just about everyone does.

I will also point out the armor/mr gain from his W is bordering on unreasonably high. Annie's molten shield started at 20 of each and it got nerfed and reduced to 10/20/30/40/50 and it's a shorter duration and she doesn't have the faux tankiness from an absorption shield as well. I must admit though that I like the idea for indicators on Q, I hate guessing at what 600 range actually equates to in the game. Lastly no on ultimate being unaffected or hardly affected by QSS, if you can remove Zed's ultimate, you should be able to remove Morde's as well.

I don't see the need for any substantial rework because he comes out ahead of most lane matchups unless it's a bad matchup for a melee top laner in the first place. Even in that case the shield from clearing minion waves prevents you from getting poked out hard. At any rate, those are my opinions on the matter
