Either the range or the cooldown of Phantom Walk need to be changed. 425 blink every 2 seconds?

Vayne has a 300 ROLL that cannot surpass walls.

You could add a mechanic that increases to cooldown of the spell by 1 second each time you take damage while it is on cooldown, up to a maximum equal to it's cooldown. This would make it better durring offensive attacks where you don't get hit back, but weak when trying to get away.

By adding that there would be no reason to increase the cooldown especitially given it's energy cost.
