I still think the best solution to this is to have a popup come up when you queue for the MSQ roulette or specific queue for the 2 dungeons. In the popup have it ask if you will sit through the cutscenes, if you say yes, you are grouped with others who said yes. If you say no, you are grouped with others who said no. If you said no, all cutscenes are auto skipped, even if you've never watched them. If you agree to watch you get increased rewards, if not you get standard rewards.
