As brought up in various Skype chats, if someone wants to make a motion and submit a Player Request for the other ID's to be brought back, then go ahead - That's what I did with the Researcher ID. I Created the discussion, and it was put forth to an Admin vote, that I didn't vote on. I acted as a Player in this regard, not an Admin. So there is really nothing stopping anyone from submitting a Player Request for a Mercenary ID, or Vigilante ID, or so on and so forth.
