I haven't played against a terribly large amount of Mordes, but your proposed build seems excessively tanky in comparison to what people currently like to put on him. Most notable it the absence of WotA, which seems pretty key since he can't refund the health cost from his spells outside of his ult.

I think people feel it is a nerf since currently people build almost full ap and rely on the shield's damage/AP conversion, allowing them to be both high damage and super hard to kill. Now Mordekaiser will be pressured into grabbing more tank stats to make shield effective, thus reducing his damage. Maybe you should try the comparison with a different build, one that is more damge focused and less bruiser-y.
