Pro tip- besides getting red in the face, raging with tears and their eyes and rolling their face across the keyboards, the players QQing about you watching cutscenes really can't do crap to you. What are they going to do: report you for griefing because you decided to play the dungeon the way it was meant to be played? Good, I hope they do! They can enjoy their couple day ban for abusing the ticket system and wasting the GMs time

If you want to watch cutscenes, watch them. Let the ragers rage and the haters hate. At the end of the day, it's not worth spoiling your gameplay to save them less than 3 minutes on their run.
