Change to Mordekaiser's W
So Mordekaiser has the slowest base movement of all tanks/bruisers. He has no gap close like Riven or Wukong. He's almost there but the problem is he is outran by even mages simply because they get things like Luden's which far outscales the MS of Deadman's. Full Deadman charge with boots and 4.5% MS and you're still only looking at 440 MS compared to Skarners 538. So this is how we fix this.
W Changes to casted on ENEMY champions. Remove ally minions and champion target. Damage remains and movement speed remains the same as long as he moves TOWARD the enemy champion.
Smallest change ever might actually make this 330 MS champion viable again.
