I've always suspected that proximity chat was scrapped from the game because it might have hurt player immersion. Regardless of why it was excluded, I'd like to recommend a solution. The current system of joining a fire team or party is just awful. I've never felt so lonely playing an online game as I do in Destiny. Instead, my idea was to put the Dance/Sit/Point/Wave buttons behind one of the D-pad directions, then use the other 3 directions for a simple point-to-point voice channel. This way Patrolling, Missioning, or even Striking guardians would be able to decide if they want to team up for a bit, without navigating the console's menus or joining a fire team to have to RTO before reloading the area they're already in. I'll leave to details to the experts at Bungie. If this has already been suggested, consider this my +1. -jake
