I dont have a link to source this, but ive heard that because of the way they made the change there can only be one version of these dungeons and one version of their cutscenes. Thats why even if you go to the inn to view a scene later, it still auto-advances at the same pace as in an actual run. So that probly isnt possible. It could also lead to people kicking newbies from groups so they could skip the cutscenes and get out of the run in less then half the time for the same basic reward. This change was always a mistake. The roulette should have been scrapped and the dungeons should have become solo instances. That would have fixed all the old problems without creating new ones. Im not holding my breath for an actual fix at this point.
