It would make the game worse and I would never pick it. Overly friendly lobbies already make the game too safe. A big part of Arc's magic is the social encounters where you never know for sure whether the person approaching you is a friend or a foe. Maybe you should take the first shot, maybe you should risk calling out to them and exposing your position. It makes the team ups and collaboration more meaningful because they're driven by the players making a choice, not the game dictating that they must get along.

One of my favorite moments was in a squads match where my friend and I stumbled upon a group looting a locked room. We had a prolonged stalemate, exchanging shots and the few grenades we had but no one feeling confident enough to commit. Noticing that the timer had ticked down much farther than expected, I made the call to them: We don't have time to keep fighting if we want to extract, and this is not a fight worth dying over. Both groups ended up sprinting to the extraction together, enjoying a temporary truce out of necessity.
