Mordekaiser rework concept

Ok so we all know Mordekaiser needs another rework and its hard to keep Mordekaiser the same since hard to balance his shield so I say we should do away with that passive all together and put power back into his kit my proposal I can't come up with new passive riot likes interactive passives Q Mordekaiser slams his mace into the ground with great force creating a fissure in a line dealing damage on initial impact and slowing all in the fissure W Mordekaiser releases a burst of shrapnel from his armor dealing damage to all enemies hit on the way out after a short delay the shrapnel returns to mordekaiser dealing damage too all enemies hit reduced damage to enemies hit more then once E Mordekaiser rips the souls from enemies in a arc in front of him healing some amount of health R the same ult maybe slightly less damage longer duration and allow it to persist through death like other pets
