I seriously doubt 7.0 will be the reset people are hoping for. In order for that to occur, the devs will have to admit that the current game is as wrong as some in the community are making it out to be.
No where in the marketing nor LLs or interviews does Yoshida ever acknowledge the major problems that people have been clamoring for years (minus a very few). I 100% guarantee that Dawntrail will be just the same safe, consistent and predictable content we have had for the last 10 years or so. They've already outlined what is coming with 7.0 in the keynote and people hoping that somehow the entire design of the game will change is nothing but folly. Again, in order for the next expansion to be very different, is for them to realize that the game is in a terrible state.
Its just the truth of that matter. Whether we stay on the boat or just jump off or stay and continue to be bitter about the game is up to everyone.
