The technology already exists for this, BB have the semi-regularly used voting for guild shop items, so for this suggestion the delivery mechanism already exists, it purely relies on the want from BB
So my suggestion in detail is as follows:
Semi regularly, say once every two months, the mods get together and pick up what they feel are the items the community, on these very foruns, seem to think are most noteworth as bugs / suggestions etc.
So maybe star stacking, guild quest issues, away from keyboard indicator etc
They would select 2-3 items
BB would also suggest 2-3 items, maybe changed combat system, a new adventure, more uses for beans, faster roll out of lvl 6 buildings, etc
Then BB would open the vote, in exactly the same way as they use for guild coin shop changes. After the open period they would have a lovely snapshot of what a good chunk of the player base feels is the most valuable from that list.
Not from the vocal minority as inhabit these forums, but the non-vocal majority.
They would then know which item, or maybe 2, would give the best positive back to the game, and hence make for happier players.
All it takes is the will from BB to engage us players at that level...
