This idea is a combination of the surveys for content shown on Lammania and bug reports. Basically a survey in which one can suggest a change to something in the game, such as items, guilds, quests, classes, spells and enhancements. The part of it that's like a bug report is how you select from the items in the previous sentence, then describe why it's not fun or unsatisfactory. Then, Turbine can, perhaps monthly, sort the reports and see which parts of the game need changing.
To prevent abuse, however, it would be necessary to log into the forums in order to fill out the short survey. Furthermore, each account/player would be limited to being able to fill out one survey every few hours or even days.
Here is an example:
What do you think needs to be changed?: Spell
Spell from which class?: Druid
Name of spell?: Fire Seeds
Why do you think this needs to be changed?: The cast time for this spell is too slow. I get better damage numbers by spamming Produce Flame.
