I don't know if this has been said already in the thread (too many pages to read) but Square Enix and Yoshi-P should consider to create an algorithm as a good fix that would check if possible at the start of the mission if people have or not already cleared the dungeon :

- If all the people who are running the MSQ Roulette have already cleared the dungeon make possible to skip the cutscenes for all members of the party.

- if at least one people hasn't cleared the dungeon make impossible for all the members of the party to skip the cutscenes.

Can't believe they didn't think about this already when thinking about making unskippable cutscenes for improve the experience of the new players...
