So IDK if this has been suggested before, but the easiest way in my mind to promote teamwork is to add a Friends list system, if you go to a server, salute a random and he salutes back, have a fun time for a few hours and generally work well, you can add him to a friends list, the list is tracked by the base game license so say his name is Bob, when you add Bob your friends list will say Bob If bob changes his profile name to Tim it will say Tim (Bob) to allow you to know it is Bob playing under a different name This could also solve the "no name accidental friend stand-off/kill" servers by adding a green dot next to or in place of his name while playing, that way you can tell its a friendly on a glance Alternatively you could add a Bandit-list for players you dont like, adding a red dot next to their name on sight, but I dont like this part of the idea too much because it would cause too big of a meta game with experienced players (longer lists) and disallow people from playing on both Bandit and Carebear accounts lastly, perhaps in your friends list you could add a Bandit Toggle, so your profile would say to other people that have friended you Tim (Bob) -Bandit- and that would allow people to know your not grouping and not be too dissuaded with your actions should you kill them in your same server (you gave them fair warning afterall)
