Other way around. Blackthorn Morgana's Dark Binding animation has a more obvious start, so you can dodge it better.

Pulsefire Ezreal has a more obvious Windup on his q, giving better ability to dodge it.

If you want an advantage for a skin, I don't know of any more extreme than Ravager Nocturne used to be. The tethers on his fear were nearly invisible.
