What's the difference between a Morgana Q and a Nasus Wither?

I don't know if this is a real question or not. But anyways.

Wither is a Movement Speed and Attack Speed slow While Morgana's Q (Dark Binding) is an Root which doesn't reduce slow effects. If that was the answer that you were seeking for, glad to have helped.

Morg's can't keep you perma-locked.

Nasus' slows both your movement and attack speed, but you can still move and use dashes. His also never misses. Morgana's roots you, making you unable to move or use dashes, but you can attack all you want as long as they are in range.

You have to hit Morg's binding.

Some one said this in a game after he got withered... I could not stop laughing.. Nasus was not fed enough to drop the kid fast so he chased him and withered him numerous times..Was one of the most funniest things to watch.. The constant BS..
