Mordekaiser need more cooldown reduction
Mordekaiser is a mage and his power consist in abilities. So 4s for Q; 12s for W; 6s for E and 90 for R is too high cooldown. And a lot of items who can be good on mordekaiser have MANA. But i have an idea: add a passive for ultimate at lv 2 who give 5 cooldown reduction for every 250 mana bonus from items.
