Anyone playing FFXI or FFXIV knows that they are part of the Final Fantasy series. Final Fantasy games are JRPGs, and thus the focus for these games is on storytelling. If you're playing this game and have no interest in experiencing the story, it's pretty much a mystery why you're playing at all. There are other, far less story-focused MMOs out there, very likely with much better endgame, battle mechanics, PVP, etc etc since the development focus will be on those aspects rather than story.
I think we can agree that at least the majority of folks that play FFXIV have an interest in the storyline. CM and Praetorium's cutscenes, boss battles, and even aspects of the trash-clearing (for example, the armor ride) are all part of an overall narrative. In the cutscenes, you learn WHY you're messing with spotlights, and WHY you're fighting such-and-such boss. Skipping them interrupts the narrative flow - even watching them later in the inn doesn't fix this. It's like reading the even-numbered pages of a book first, and then reading the odd-numbered pages later.
SE's heart was in the right place, but this wound up being a terrible, terrible design decision. They wanted an epic, story-rich final confrontation with the Garlian Empire, with a full party to handle greater challenges. They also wanted to ensure that these newbies would always have help available, and so made these dungeons a great source of Philosophy tomestones (later, Mythology). They learned well from FFXI that it is VERY hard to get folks to help out with older content unless there's a significant reward involved, so it was the right decision to make - even helpful folks will tire of repeating it after a while.
While it did work, and newbies can still find ready help with old content, SE made CM and Praetorium maybe a little TOO valuable a source of tomestones. As with all grinds, folks immediately went to work perfecting ways to make the grind more efficient. Skippable cutscenes in a grind dungeon? By far the most obvious corner that can be cut!
It is absolutely laughable to think that ANY representative from SE would ever consider a player, on their first time through the dungeon experiencing the content for the first time, to be "harrassing" the other players by wanting to see the story. To use the kick function in such a way is a clear abuse. That said, it is understandable why folks trying to grind the dungeon would be disgruntled by having to wait.
Fortunately, that SHOULD no longer be an issue. Brayflox Hard is a more efficient way to grind Myth. You can get 150 Myth pretty easily in the same time that you could complete a single Main Scenario Roulette. This means that anyone truly interested in speedy acquisition of Mythology tomestones will be doing that instead. Anyone signing up for Main Scenario Roulette is doing it either specifically to help newbies, or for a change of pace from the Brayflox grind. The former should be more than happy to let newbies watch cutscenes, and the latter is already accepting a slower pace than they could be getting, so why should they complain? (There's probably a third category - vets who were forced to skip before, who want to see the story done the right way.)
At any rate, things should be improving. If they're not, maybe it'd be best for SE to make the cutscenes in that dungeon unskippable (or, at least, make the bosses inaccessable as long as anyone is still in cutscene) and to boost the reward to encourage folks to continue to assist. It's frankly obvious that SE WANTS players to watch the cutscenes, at least once, or they wouldn't be there in the first place!
