An updated Mordekaiser rework
He needs a new rework. Here are my thoughts!
P: Make this function like a reverse-bloodthirster, where when he has a full shield, he will gain some amount of life instead of building more shield. Increase the healing vs champions just like shield generation is increased vs champions.
Q: Make this ability single target for spellvamp/etc., and make it work with stuff such as sated devourer, titanic hydra, etc. Reduce the effectiveness to 1x-3x-6x instead of 1x-3x-9x
W: Remove the XP passive completely. Make it castable self, ally champs/minions, and cursed enemies. Have the DOT always present on self, but only activate for the 2nd target if it is touching Mordekaiser's aura. Keep the attraction speed bonus Remove the on-use heal. Give it slightly bigger numbers to compensate for the loss of the big hit on-use
E: Keep it like it is
R: Keep it like it is, but it has a new interaction with W to help him chase targets
This would give Mordekaiser some better engage with the ult + W interaction, but unless he sticks to the target, they won't take damage from W since the secondary damage field would not activate. The frustrating experience bonus is gone, removing the invisible and artificial power. Mordekaiser gets some sustain based on his damage instead of gimmicky spell usage, and he stops giving stupid sustain to his duo lane engage partner. Spell vamp works better so he can have more carry-like sustain, with a little extra sustain if he manages to fill up his shield. Also, this lets him work in a solo lane again.
