I'm confused about what you are complaining about with this thread? Is it the ARR bit before HW? If it's really that bad to you, skip everything. They've fixed it recently but I'd argue that it's one of the worst parts of the game.
Do you mean that you consider everything in patches after the main expansion to be filler and unnecessary? All the MSQ dungeons (which are in other Roulettes) relate back to the main story, and it's like going through a dungeon in a single player game, only now you have 3 other players with you. (And if you don't even want that, now in Shadowbringers you can bring 3 NPCs to run with you).
Are you saying story is unnecessary in general and a "scam"? Well, this is a FF game first and foremost, and what makes it different from other MMOs. I know people who skip everything cutscene wise and just hang out everyday; that's their choice, much as it is my choice to enjoy it and do dungeons. Both of us enjoy the game because we play it the way we want to.
