You can win with on-hit but I don't think it's optimal. Bruiser works better vs tanky teams. If you go for mostly attack speed items, it's hard to get enough attacks off to make them worth it 'cause you'll be quite squishy.

Duskblade of Draktharr gives you ability haste, which lets you cast your ultimate more often, and invisibility after you 1-shot someone. It also deals basically the same damage as Eclipse until later in the game, when Eclipse's mythic passive is stacked up. I'd recommend Duskblade as it'll give you more opportunities to get kills and you'll be safe from being focused after killing someone, because you'll be invisible long enough to reposition.

Generally when the enemy team isn't squishy / vulnerable enough to use a full damage build. If you're against a lot of tanks/bruisers, peeling supports like Lulu, and the enemy team is going to be grouped a lot of the time, it can be basically impossible to reliably 1-shot someone.

The Bruiser build still lets you kill people, but you'll do it over time and you'll be a lot tankier for team fights. It's not as strong at carrying, since getting picks solo is more difficult (the enemy has more time to escape or get help), but it guarantees you won't be useless in team fights.

For example, I used the bruiser build against a team with Renekton, Rek'Sai, Sylas, Miss Fortune and Maokai. I could probably kill any of those champions with the Assassin build if they were alone, but when grouped, my only viable target would be MF (and she built Zhonya's Hourglass that game). Instead, I was able to fight anyone on their team, even in team fights, since I couldn't be bursted through Sterak's Gage and had enough DPS from Lethal Tempo to kill their tankier guys.

Wow, I didn't even realize they changed the name. Thanks for the tip, I'll update the guide now.

Lethality items look pretty good but it's hard to say for certain what options there'll be. Nocturne has historically had pretty radically different builds based on which items are strong. I'm hoping we'll end up with more build flexibility than there was for Noc this past season, but there's a lot of uncertainty with PBE testing so I'll reserve judgment for when the preseason patch actually goes live.

I usually post a comment for any major updates.

I'm still testing out the jungle changes so I can't say much for certain yet. I can confirm that power farming your own jungle (without scuttlers) is much worse now. The earliest I reached 6 by powerfarming was 7:35 which is pretty awful. If you're able to secure some scuttlers and you make sure to clear Raptors and Krugs often, you can reach 6 at a more reasonable time.

I would definitely say Nocturne seems viable still, given certain conditions. Against a coordinated team, you might crumble early game if the enemy has mid priority and a strong dueling jungler like Warwick or Xin Zhao. If you aren't pressured too much early, he works pretty similar to last patch.

The one upside to 8.11 for Nocturne is that snowballing is a bit stronger now, since killing spree shutdowns are less punishing for the team that's ahead, and shutdowns now grant more personal gold (and no team gold), so if you're able to kill a fed adc, you get a bunch of gold for yourself. It can be easier to extend a lead if you're able to get rolling since if you die once you won't give the enemy team a huge gold bounty.
