They're not going to change anything unless they start losing money. If people keep buying expansions and stay subbed there's no reason for them to change. They're fine with angry players on the forums as long as they're still paying.

I cancelled my sub a couple days ago and am just hanging around to watch the drama until it finally expires. My sub never lapsed since I started in early Stormblood, but I can't tolerate what the game has become any longer. If they want me back they either need to make the story engaging, make the story optional, or make healer gameplay involve more than spamming one button for 90% of every fight. Any one of those three changes would be enough for me to come back. I'm not optimistic.
