I know the feeling because I've thought the same thing about every major MMO for many years now.
I'm looking forward to FFXIV 2.0, but I want to suggest a new MMO to you guys that you may want to check out if you're looking for something truly different from what we keep seeing. If you're bored of the same concepts, check this out.. It's very different.
Trials of Ascension. That features section does absolutely no justice to the game. There's is so much more. Magic is not common and extremely difficult to aquire and learn. Nights are so dark you need a torch. You have to eat and drink or you'll starve. Maps don't tell you where to go.. in fact you can be a cartographer and map areas out, selling your work to others. Environment is a factor. Want to cross a desert? Bring a lot of water. Build a house anywhere you want, or make a village with a group of people. Or a castle once you have the money. Live as a thief, break into peoples houses / or hunt criminals... etc etc etc All of that is tied with perma-death. You get 100 lives, so don't waste them. That is the kind of game it is.
If you think the current state of MMO's is stale, particularly if you're a fan of the old sandbox MMO'S, this may be exactly the kind of change you want. There's still a long way to go before this game is close to release, but I'll be following it every step of the way.
