With every community, there is a loud minority, and a silent majority. When changes are being made for the loud minority, people from the silent majority speak up and say that they don't like the changes or would prefer it in some other way. To put it simply, the feedback we are sending is a jumble of mixed signals, not helped by the way feedback is received.
You can see this with the recent 2 Minute Rotation feedback and response. Some people really like the change, some people don't. My opinion on the matter doesn't really matter, as that's not what I'm talking about here.
Forums were excellent several years ago, but times have changed. While I think the forums should stay as a method of receiving bug reports and more long-form feedback discussions, there needs to be an easy way for in-game players to participate in providing feedback.
I believe the way Genshin Impact does this would work well for FFXIV. Using the in-game mail system, players are sent a link to a feedback form they can complete about recent additions and changes. If there's something being brought up in the forums a lot, a form can be sent out about those issues too. The forms are usually a mixture of polls for various issues as well as areas you can write out feedback in more detail.
As an example, if the developers wanted feedback on job balance...
They would sent out a link to the feedback form through mail. By clicking on the link inside the sent mail, they would be taken to a web page with a series of questions. The first few questions would be multiple choice:
1. How do you feel about the current 2 Minute Rotation change?
A - Strong Like
B - Like
C - Neutral
D - Dislike
E - Strong Dislike
X - Don't Know
2. How do you feel about the current state of Healers?
A - Strong Like
B - Like
C - Neutral
D - Dislike
E - Strong Dislike
X - Don't know
And so on, and so forth.
Of course, multiple choice isn't perfect. So, after each question or at the end, there would be short answer sections where you could explain why you chose what you did.
But this is not enough.
After a form is sent out, around two weeks afterwards, there needs to be an effort to ensure there is a compromise. If one particular type of player wins out in the polls, the others deserve something too. For example, if there was a heavy favor in jobs being unique, then jobs would still pump out a minimum amount of DPS so they could remain viable in difficult content- similar to Stormblood's balancing.
I think, ultimately, this is the best way to go about receiving feedback, and will be good for the future health of the game and its community. Everyone's happy, ye?
