I believe you've missed the point of MSQ roulette.
The duties in there are the ONLY duties with long cutscenes that constantly play during the experience. While SE admitted this was a bad idea and has promised never to do this again since it created a disparity of people who were doing the story and wanting to watch them and people who were getting the dungeon and skipping it all to finish faster, they've kept them because they're arguably a enjoyable part of the story for first timers and the work to change them would be better used elsewhere. They were put into their own roulette and then later made all the cutscenes unskippable so that people couldn't be rushed through it. The roulette is there to help people finish MSQ. If you don't want to run those instances.. don't queue for it.
