i think most of the time, active players in any game is solo players, so any mode that is based on friends or clan is a bad idea , it may be good for the first few months to any game, but after that,i am sure all active players is solo, causal players, u have to focus on these players with some adjustment, like matchmaking. even some is playing the game as a clan before, after several months, they all become solo player. that is true , no doubt .
