Guild Wars 2

The “New topic” action would open a form like this but instead of a big text area I would add some specific text areas with a limited length of characters for each and other controls such as the graphics for votes count. This way every thread has the same format.

Title: text box 100
Category: Drop down list (Living story, general PvP, general PvE, class, etc.)
Can be replied: Check box. (if you just want to check the votes and avoid the discussion). This would limit only common users because a dev should be able to say “this is not possible because… game engine”.
Description: text area 250
Votes count: horizontal bars with %

Every month the dev team could take the most voted (feasible) suggestions and implement them.

ANet does not have to “guess” what their customers want. With the proper communication channels you could avoid forum intoxication, give your customers the tool to tell the dev/design teams what we are expecting from the game to be enjoyable, lasting and focus there instead of trying to find the silver bullet and going through the experimentation method in every change implemented. Happy customers yield more profit obviously. More gems, new players and a healthier community that thinks and knows the company cares.
