I think the issue stems from 3 factors.

  • The gear treadmill and daily roulettes incentivizes running the dungeons ad nauseum, which already sucks the fun out of doing them bit by bit. As such that would mean people take an in and out mentality,leading to mass pulls and such
  • The Dungeons grew to be as linear as XIII over time (ARR ones weren't as linear until maybe level 50 and one in particular had multiple paths) and pulling multiple packs proved to be easier and easier as time went on. If anything the content seems to have a general concept of mechanical density where the short an instance is the more mechanics and difficulty would be piled on, with the possible exception of Alliance Raids
  • Furthermore the number of players that had played since earlier content cycles even some going as far back as 1.0, would mean that there are players that had already ran the content multiple times.
All of this means your best shots at a more scenic run lie with finding a FC or Linkshell with like minded people ro making a PF for such tasks
