" Mordekaiser is a juggernaut"
Why can't he does great damage while building tank then?
he needs 2500 HP to break the old shield but if he build health, he won't be able to complet the shield since the shield generation is down from 35% to 25%.... Not forgetting that the base damage of his E is down from 250 to 150, seriously? Why is he getting an AD bonus on his E? you said in 5.4 that AD morde isn't a thing. And the cooldown of his Q was increased. He also lost his armor/mr bonus on his W.
All i see is a carry hybrid mordekaiser, there is no "immobile tanky great damage dealer" champion.
