Ranking people based on a proficiency level seems a bit off, as maybe the one with the most insight into a proficiency realized before others that grinding it to a high level was not needed. Also, what about someone who grinded a skill from 150-600+ in two weeks because of resources available and a desire to now do that trade? While he may have an insight, should it be held to this level of esteem? If you leave that discretion up to devs for the final roster.. .then why not just make your roster? If you want to pick and choose, you can already do that without seeming to open the discussion up to all. Certain personalities will be criticized regardless of quality of input.
Perhaps you should give these titles out in the form of a forum account with that title. Allow the users to post from those accounts. I do not see Claeyt or Heff's ideas being given the time of day regardless of what title you give them. Make it anonymous to all but a few, JC, Meow and Marp.
