ayyy no matter how much "new" or "different" content they will add or how fast they will do it, people will go absolutely nuts, and farm everything they can within the first week or two. Then it just becomes another boring content again, and players will be back on the forums/reddit, complaining how they have nothing to do, and they need new stuff. Let's face it, grind, no matter what kind, will still end up a grind, no matter how different. Gold Saucer was new and interesting, people couldn't even teleport in and out of the are for a good half a day. And now it's basically a ghost town. Everything is interesting when it's new and sparkly, but yea, grind is a grind is a grind is a grind, and that's what mmos are built around.
