Just my two cents here on PF. I'm on Jenova. We have like 8k players total, and only like 400 on at a time. a pf for cutscene watching story mode, would take not hours, not days, but months to fill if ever. lower population servers rely on df, because our pf's aren't always reliable.

that said, I just skipped the cutscenes my first time through. I watched a "lets play" on ffxiv before I even started, so I already know the storyline.

"watch the cutscenes elsewhere" should be part of "read guides before you enter new dungeons". I never go into a dungeon unless I have read and watched at least 2 sites or videos detailing the entire dungeon from start to finish, so I don't screw up and wipe the party. I expect others to use similar preparations, so as to not be a toxic party member.
