I can honestly say that I personally rarely check the Feedback. Once upon a time, when Graal maxed out at 150 players, I would read it constantly for improvement ideas. It was a glorious time of growth and development, new staff members every week and watching the player-count rise person by person was the passing sport on RC.
Today's horizon is that of a new era. The Dawn of the Spam, as I like to call it. The majority of the crap sent through Feedback is just that - crap. I don't enjoy receiving feedback on how we should "ban Fancy Pancy Nancy bcuz she stole my look". I revile in the thought of Feedback. I almost (read: I really don't, but for theatrical sake) shed a tear whenever I half-read a good idea via feedback, but alas, it is utterly stabbed, kicked, pummeled, and ganked by ten individuals from the same guild that are requesting a staff member come take a picture with them in their guild house.
The moral of this story: Send your ideas via e-mail, facebook, or graalians PM if you want to get to me. Feedbacking, or PMing me in-game, will ensure the sad, sad destruction of your idea.
