Just so you aren't mistaken, we don't really have a single individual leader, anyone who wishes to take more of a leadership role is allowed to do so within the team, and all decisions are discussed and then agreed upon with all active/present members of the team.
Secondly, If we were to do this there would be no point in making a "separate" team to build the single player, we would just recruit people with the time and knowledge into our team with the task of designing single player missions and such.
