I saw it it swtor beta and i find it a very good idea.
Why not Anet puts an ingame survey tab, where they ask anything they want about their game and getting some real feedback.
It can be done in a new tab/panel where players can open and fill it,or ignore it as they please.
They can change it frequently to gather more data for all aspects of the game.
That would create a larger pool of information since not all players read and post on forums and to some point it will help to make the game better and even more enjoyable.
Just a thought
