All user input is useless when it isn't factored into the design. Then again, who'd want to let their work be dictated by amateurs? In the end the devs have to do the work. If it doesn't please you it just isn't the game that you envision. My own painful lesson from the release of engineers was that all they care about is soulless grind gameplay for peowercreep.
i dont think it's just a matter of a conflict in vision. I think fdev doesn't have a cohesive vision for the game...where each decision or choice in new features is building towards that vision to create a game that that person(s) would enjoy playing.
Perhaps instead of a set group of players, fdev could do something like implementing a weekly survey that is randomly sent out to a fraction of the players who have been active in the past 2 months. These surveys would ask targeted questions about current and future game design items that are coming up in a vague but still valuable way.
This would allow fdev to at least get an idea on what they're doing right or wrong before they get beyond the point of no return.
questions like :
1. exploration needs dangers but only in certain scenarios like around certain kinds of planets or stars (pick 1 do not agree at all to 5 agree completely)
2. Trade should be adjusted to personalized mission opportunities and not a commodity board, allowing buy or sell orders to be made as well that are unique to players based on reputation and BGS (1-5)
3. Foot combat should reduce the importance of shields and high/no ammo weapons and focus more on targeting skill (disabling particular body parts and eventual healing of them to avoid outright murder if desired - and thus skip getting bounties) and strategic use of limited ammo. (1-5)
and fdev could track all the responders and tell if they're heavy explorers, traders, foot players or a good combination of them thru actual in-game data. Then they would have a good visual on what those kind of players want and how to design features that impact those players the most in a way that those players would like them to function.
I think if they cared about improving the game experience something along those lines seems necessary because what their current process is, is lacking and frequently out of sync with players across all spectrums.
edit: Now if only we can go back about 5 years and implement this then, when it had any chance of actually happening.
