What would make it even less complicated is a "Party Chat" setting, that when turned on simply required the wave emote (d-pad up) when targeting a player to invite them to a party, one need only target and wave back to join. Parties could contain as many as six players, only connect for chat, and have no effect on strike team composition (you could toggle chat to party or chat to team chat in the Nav Menu with LT). This wouldn't need an on screen prompt other than the text that is already present on screen when using these emotes on a target already ex: "[b]JoePro[/b] waves to [b]CaseyCasual[/b]". It'll just be understood that waving back adds you to a party chat, and maybe give a in game hint/tip the first time it happens so players can know what that does. To leave a party you'd just use the wave emote again targeting a party member, drop party automatically when you go to orbit, or just drop party from the Nav Menu by holding the LT for 3 seconds (identical to how Call Your Sparrow and Go To Orbit buttons function). Parties would always be additive up to 6 players, E.G. a party of 4 could merge with a party of 2, and so on. This feature would be disabled in PvP, but be replaced by automatic chat with your team. It would have a setting in the settings menu for Crucible chat on/off (default off), and individual players could be muted as per usual.
