PASSIVE Gain 15% bonus movement speed toward movement-impaired allies or enemies you've impaired ⇒ Gain 7.5% bonus movement speed when moving toward a movement-impaired enemy champion. Increased to 15% if you were the one who impaired their movement (There is no longer a maximum range of 1000 for champions that you have CCd)
Isn't this a nerf to Approach Velocity?
So it used to only give you MS toward enemies ONLY IF you ccd them which a lot of people didnt realize. Now you get the same MS if you've CCd them, but also get some MS if someone else CCd an enemy
