Idea for Mordekaiser Rework

One of the main problems when fighting Mordekaiser is the fact that he can just click W and get a huge shield that lets him survive much longer than he should be able to. An easy way to fix this is make it so W gives the player a fixed amount of shield based on the ability level. This makes it so people will have to choose between maxing E next for the cooldown reduction or W next for the shield. This will balance Mordekaiser by a substantial amount and reduce the whining. To compensate for Mordekaiser losing a huge amount of survivability during fights, Mordekaiser should get increased armor, magic resist, and tenacity during the duration of the W.
