One very simple suggestion for Mordekaiser's W
Instead of allowing you to W an ally to armor them and gain speed when walking towards each other (Which isn't all that good for catching or running from someone),
Allow Mordekaiser to target an ENEMY, to directly deal the AoE DoT and gain movement speed towards that targeted enemy instead.
I think this would help balance out any damage the Rylai's changes will do to him.
P.S. I wanna hear what Malicious has to say about this suggestion.
