Nocturne Ult Suggestion

Since Nocturnes cooldown for his ult is basically about three complete minute. I've seen people say that his ult is basically un-rewarding and not really giving the fearful effect it once had when he was released.

What if Nocturne got a new ult effect besides tunneling your vision.

ACTIVE: Nocturne reduces the sight radius of all enemy champions and removes their shared vision for 4 seconds; this includes champions, minions, wards, towers, and Clairvoyance. While Paranoia is active, Nocturne can activate it again to launch himself at a target enemy champion within range**, also fearing them for (?) seconds, any enemy champ Nocturne flies through gets feared for (x) amount of seconds(basically anyone else hit is feared less than the initial target)** dealing physical damage.

What'ya guys think?
