Maybe there is a middle ground. Perhaps they can add the "Duty Complete" to the Duty Finder Settings. That way, those people who generally want to skip cutscenes can just enable that setting and they won't be grouped with any new players. They'll potentially miss out on the bonuses, but that is their tradeoff for no cutscenes. If you don't have that setting enabled, and you get a new person, then cutscenes can't be skipped.
