There is no single content design that is enjoyable to the vast majority of the gaming audience. You're talking about billions of players world wide.
The design does appeal to some, though. It only takes a hundred thousand players to make a MMO profitable (assuming the developer isn't spending wastefully). As long as this game finds that 0.005% of the gaming audience that like "the dance" for raid design (or that audience finds this game), FFXIV will continue to be successful.
Players need to learn that it's up to them to find the games that have the content design they want to play and then support those games. Developers aren't going to waste their time struggling to meet the varied expectations of players who want a different game than the developers are trying to make.
Giving money to a game that isn't delivering what you want sends the wrong message to the gaming industry about the type of content you're looking to play.
