mordekaiser buffs?

i think that mordekaiser could use few buffs because after you changed items to give more armor/mr and less hp his passive got weaker so i would like to see some buffs to his hp/lvl or bigger % on his shield. and maybe some %hp ratio on his w heal bcs when build as tank with only 100-150 ap and 3-4k hp heal is only around 400 vs 2 champions, 50 vs 2 minions when you count the hp cost. and btw mordekaiser wasnt changed when spellvamp on was replaced by dmg so some changes to him would be nice
