If I look at Mordekaiser, he should be a bruiser which has a hard time to get to you thanks to his huge armor but if he gets there, you are sure to be dead. This is basically the thing why his his shield should be like that. If you read carefully, he can now only cast that shield on himself.

Also, remember if you look at his ultimate, the only real way for him to deal damage now is to get close to you and smack you to death, as his other spells lost a great amount of damage. This balances out the fact that it is hard to escape from him as long as you don't burn your defenses.

About E beeing instant, why it shouldn't be? The counter of it is to stay out of his range, which isn't really that big. And even if he hits, the damage isn't that high and 15% slow is only good to get a little bit closer.
