Not in Crucible? Are you someone that plays with friends, and is trying to keep it imbalanced so that communicating players can roflstomp everyone else? I agree in terms of people outside of your team, but in-team chat is so essentially that it's basically a given in every other game with group PvP.

It's essential in theory but my limited experience had always been two guys talking about something unrelated to the game the entire time or some dbag listening to music or just yelling at everyone for sucking. It may be a pain but you can add everyone in your team to your strike team in orbit. Sure you can always mute the dbag but everyone else still hears him and sits there quietly because of it. Picking and choosing who you hear may not be what every other game does but that's what Destiny is aiming to do. You have to add people and then you discover they're cool and then you friend them.

How can you get through all 6 players before the game starts? And how can they rejoin in fireteam before the game starts? How is inviting everyone functionally different from starting with talkiness as a default and muting people that annoy you? Besides being super annoying and adding several rounds of loading screens, I mean.
