Thank you for the review! Responding to some of these points:
 * I'm not the biggest fan of stealth in its current implementation, which is why I suggested a change to stealth and vision here, and I think it might be relevant to this concept. Basically, I agree that stealth has no real counterplay now, and I think it needs to have an inbuilt mechanic that allows all champions to interact with stealthed opponents better, all while removing hard counters like true sight. The idea here is that Nocturne's stealth would be limited to a set area, which would make detection far easier, and would be limited to a short duration (3 seconds), meaning there would be very little abuse potential to his stealth even without counterplay mechanics in place.
 * The synergy between the stealth on Q, passive and fear on E is intended, as I want Nocturne to be good at jumping from blind spots and jump-scaring enemies. There is clear enough counterplay to this, via either warding or staying well away from low-vision zones (including Dusk Trails), that Noc's ambushing power should be somewhat predictable. It is also worth noting that movement speed past 490 is reduced by half, so Noc wouldn't be going as fast as what you listed (though still pretty fast).
 * I think dropping the dash on Paranoia would better show what makes the ability special, since it is most infamous for its ability to deny vision for several seconds. While global utility isn't considered an assassin skill in the overall framework of League of Legends, I think darkening the map is the perfect assassin ability, since it sets up ideal ambushes. Considering how Nocturne will always focus on one target, and will have movement comparable to that of his dash, the feeling of having a member of your team (or yourself) about to imminently die during the darkening period would remain. I also feel Noc would still keep a power spike, even if it doesn't directly express itself in damage: Noc would always deal increasingly more damage, but his biggest power comes from his ambush potential, which his ult would massively increase. Effectively, his ult would allow him to assassinate increasingly better, just without having to resort to damage.
