After playing the game for a week now, with my friends and I normally on at different times, we normally end up playing alone. I have to admit, lack of proximity or any simple game chat is completely isolating and weird, and it is starting to spoil the game play. I get that some people will always troll, but the option to mute them solves that issue - so saying no in game chat is to stop trolling is a moot point. I love the game so far, but no fireteam chat or proximity chat during an "event" is brutal.
