I get that you limit the open battlegrounds have a player limit with all that the servers and systems have to process, but the Tower is a place of social interactions and not pounding one's fist or knife into a Dreg's face, so why the same limit of players for kicking the Darkness's ass as wave after wave of enemy rush towards you as kicking virtual soccer balls at dancing strangers? If our nice new-ish Xbox Ones and PS4s can handle 64 players shooting the living hell out of each other in BF4, I'm pretty sure they can handle 64+ players silently dancing in place while you look for new friends to join a fireteam.
