Crazy Idea for a Mordekaiser change.

What if Riot changed Morde's resource to mana? Kept health costs and everything else the same, but instead of "shield" he had "mana" that he would lose before losing health. Same functinality, but allowed him to build different items. Or actually make some items he uses already more useful.

All you would have to do is make his mana regen a negative number and voila. Still degenerates just like his current shield.
