Personally, I would like to hear more friendly chatter. It seems to me that many people either don't have anything to say or feel uncomfortable talking to strangers (I prefer the latter), which seems odd to me simply because the game is designed to promote random interaction. Playing Destiny and not being social (especially when you're matched up with random players for strike missions or in the crucible) seems pointless. Skill will only take you so far. Communication is a big key to success.
