I recently did the roulette because I had already gone through everything else that day (rare for me lately), and there's one point here that I think speaks to a lot more than just the dungeons. Cut scene, take two steps, cut scene.

This is present throughout the MSQ. How often do you get through a cut scene, only to be stood right in front of the NPC that finishes the quest, only to start up another cut scene? There are several points in the dungeon that do this, a few of which with zero enemies or interactions, so, effectively no reason to have dropped out of movie mode at all. It certainly wouldn't solve anything anywhere, but as part of a streamlining effort, feels like they could really stand to send a dev through these quests and figure out where they could just stitch some scenes together to speed things along.
