Darkness is a little to underwhelming

From what I understand Riots initial thought processes of buffing nocturne is to increase the duration of his Unspeakable Horror (E) is to increase it by .25 seconds at all ranks. Honestly though this is kinda sad to be even considered a buff. It's more like an adjustment that should have been done a long time ago. Really now in game Nocturne's fear is a channel that takes about 2 seconds and would only gain a millisecond to the fear. That's basically nothing at all. To consider this a buff, the duration of the fear at rank 5 could at least be 3 seconds. Also considering his ult, it's a mediocre Rengar ult. Losing all vision on the map and a long ranged dash that can be countered by walking into a bush or cc. I think we can all agree that it's underwhelming as well. What can you do about it? How about make it like Rengar's ult and allow you to see enemies in the fog of war so you can target anyone within your ult radius or while having your ult active it can silence the enemy team so they can't use cc to stop it.
