Hopefully this isn't too meta, but right now what I'm wishing for is an improved wish list.
Right now what I see is a bunch of ideas, good and bad, that get either discussed or shot down. Either way, it seems the majority of these ideas are forgotten a week later. Maybe the devs pay more attention than they care to show, but it seems most of the ideas here go unnoticed.
What I'm proposing (more like wishing for) is tweaking the system to get the good ideas noticed. The author posts his idea. After that, there is a three day waiting period during which the idea is discussed, flaws are pointed out, suggestions are made, etc. This period serves as a "polishing" stage. The author is able to edit his original proposal to include any fixes or tweaks that were pointed out. Once the three days are up, a poll opens, in which players can either vote "Yes," "No," or "Not yet" (indicating it's a good idea but it's far from being a priority at the moment).
To prevent players from creating new accounts simply to boost their idea's vote, we could limit voting to accounts that have a certain number of posts or that have been around for a certain amount of time (or some combination of the two).
Then, when the devs look at the wish list, they can sort it by number of "yes" votes, best "yes" percentage, etc. to get an idea of what the community thinks would most improve the game. Of course at any point the devs can decide to accept or decline an idea regardless of the voters (but I'd expect an explanation if they decline a well-received idea).
