What is there to appease? Hardcore player will extract what they want from the game content and be "done" with it once they felt they've experienced everything the game has to offer and moves on. Part of the appeal for the play style is to experience as much content in as efficient a way as possible allowing you to get the most, by their definition, out of each game. And if the developer happen to create content that might interest them again, they'll come back and rush through those in the same manner as well. I guess from the company's perspective, this is not what they want to happen because these player won't be paying monthly fee in a consistent manner which pretty much has nothing to do with the players. Let the companies running the games find their own way to solve their problems I say and perhaps one day we'll see MMOs that are designed to get around it, which, judging from its content, FFXIV isn't designed to do.
