I didn't at first, but after reading through the whole post, I feel that I agree with some of what the OP has stated, and some of the statements made by other posters in this thread.
There are a great deal of things that could be done differently in FFXIV, but no matter what changes are made, there will be groups who disagree with the state of the game. I fully agree that new content could be made more appealing and original rather than a reskin of existing content. Personally, I think there's a lot from FFXI or 1.0 that they should've retained, such as the seamless zones and slightly less easy travel methods, have actual avatars instead of the ridiculous egi for smn, a more customizeable job and equipment system, etc. I understand Yoshi's reasoning behind most of the system, and respectfully disagree with a lot of it.
That being said, this game will never be what many people are hoping for, which is something akin SAO (hate the story, love the concept) or .//hack. A Final Fantasy that is truly immersive, expansive and limitless. Obviously, that's not a reality at this point. In 10-20 years, I have high hopes that we'll see those types of games starting to be developed. For now, we have this style of MMO. It's just like every other one out there because, believe it or not, we still have technical limitations. Be it in the way we interact with the game, or the fact that it's on a 2D screen, or the limitations of hardware on players' personal computers. There is nothing SE can do that will "fix" FFXIV. This is what they have made, and the formula works. They have over 14 million players and climbing; why would they even consider doing something differently? Because there are a few threads on myriad forums that no one with the ability to make any changes will ever read? I'm sorry, but I just don't believe that's a healthy way to think.
FFXIV is really not all that bad for what it is. It's a solid game, we enjoy playing it and doing whatever it is we do in the game. There will be times where you're tired of the existing content, or just tired of repeating the same thing every day. On days like this, I play that game I've been neglecting due to the timesink that is the MMO, or try to find something else to do with my time. Take a break from the game if it'll help. Go play some other MMOs and see if you enjoy them more. Don't worry, Final Fantasy won't disappear if you go play Guild Wars for a while. I spent many years playing all kinds of different MMOs, spent years of my youth playing FFXI, had a several year love/hate relationship with WoW, tried a lot of those "Action" MMOs like Tera. At their core, all MMOs are identical, and so are the companies that make them. You'll have a hard time changing that.
