The devs do pay attention to our concerns. Its pretty damn clear from what we hear in Live letters that they pay a lot of attention to community feedback, which frankly is the most important thing.

The reason devs probably don't communicate much, particularly through their CMs, is because they often don't 100% know for sure what changes they might make and any thing they post will be taken as gospel by the community even if they stress it only might be what they are doing. A lot of the time the only answer they can give is 'we are looking at it' and most people aren't going to be happy with that.

There is also the matter of language. CMs cant give us that much info and the devs who would be working on it speak Japanese. Holding a one way conversation means the CMs just need to convert our concerns into Japanese. Having a Dialog means they have to try and do that two ways constantly which is a lot more work for both sides and frankly the devs should be focused on developing not chatting with players.

The devs have also indicated several times answers to people's concerns often up front when they see the concern approach, and people chose to ignore it. Hell other players will explain the situation and just get dismissed as 'White Knighters'.

WoW does in some ways have better communication about upcoming launches but that is because they literally spoil everything about their approaching patches months before the bulk of players touch it. I find one of the things I like about FF14 is when I play the story I can be surprised without having to completely disconnect with the community six months before it comes out. I know pretty much the entire plot to Legion and I haven't even played it.

As long as they hear our concerns in the long run that is all that is important as far as I care.
