I think what I'm actually asking is for people to play the dungeons at an appropriate tier of difficulty for their group.
I'm not the designer of Naerband, but I do know him, and it's working as he intended it to work: long and difficult. "Why would I play this one when I could play a super fast instance and get rewarded for it?" If you're asking the question then I think you've already answered it for yourself.
I don't blame you guys for our decisions. I just have the benefit of knowing why a lot of those decisions were made, so I can't get as upset about them as you can because you don't have that added context. It's normal. A lot of the time it comes from wrestling with our engine to get it to do new and interesting things, rather than the type of things it could do in 2005. Bringing it back to my own sphere of influence (because honestly, what business do I have talking about dungeons?), you might wonder why the first two minutes of the Dwarrowmoot chapter in Legacy of Durin has no voice acting. It's because our engine needed time to load in all the voice clips that get played over the course of that instance -- about two minutes. So I had to add in extra drama to let us basically chew up the clock, letting the engine catch up; otherwise it would play all the voice clips at whatever random time it finished, which of course wouldn't line up with the text.
Was it a bad design decision to not have voice acting for half of the drama in the instance? Maybe... but it was also unavoidable: not only was it discovered long after the recording sessions were done, but it's not like a new session would have solved the problem; the new VO clips wouldn't have loaded either. So we made the decision to do it this way. Decisions like this get made every day, dozens of them. Sometimes they're the right one, and sometimes they're not. Sometimes we have new people on the team that are learning new things, and sometimes we have old hands moving on to new opportunities and we need to figure out how they set up the first half of a big and complicated work-in-progress. We do the best we can!
And sometimes we do make bad decisions. Witness me wading in here to complain about people exploiting the boss fights my coworkers make, for example.
