Nocturne is played more as a bruiser than an assassin now, I don't play Noc much, but his build seems rather simple, I've seen it a ton. He has rediculous sticking power, let your team initiate the fight, and have a tanky item or two, like FM or Randuins. Either walk up to the enemy carry and whack them to death with constant auto's, an AD+MS boost, and seemingly constant fears. Did they use flash? Ult. Did the enemy send someone at you? Spellshield. His kit is literally perfect for sticking to a target, and he is very good at his job.

Besides this point, he isn't that ult reliant, you don't need to wait for it to be off CD to teamfight, yeah it gives you a boost, but if your team inititates, just flash onto the enemy ADC peel of course is the bane of a Nocturne, but if you're keeping the enemy ADC AND support focused on you, you're keeping two enemies occupied and out of the rest of your team just for your time, or maybe your life.
