I'm surprised with FQC...
And how enormous a deal it was (and how broken it was) when it first became the Spooky Ghost item that the active never got a nerf. To this day it's still a semi-global, targeted, two person 50% slow that last for 4 seconds. That doesn't require vision. And grants vision. And essentially guarantees a kill on use. On a 60-second CD.

active, please.
