Can we slightly lower the cost of Morde's Siphon of Destruction

As things currently stand it takes 76 health to cast Mordekaiser's E at max rank, making maxing it not really attractive. His Mace of Spades and Harvester's health costs sit at 36 and 65 respectively and seeing that you probably would want to use your E every time it's up makes the health cost stack up quickly.

Mordekaiser already has very low Hp/5 and base health and since his E is no longer the opressive 250 damage poke button I see no harm to decrease its hp cost to somewhere around 50-60.

It would make his E max more appealing with it providing the % max shield, giving good ol' Morde a reliable way to boost his defenses.
