I've been advocating for an in-game VoIP for ages. I get the usual "but why, when players already use ts3, Discord, Mumble, etc" from folks. So whatevers.

Maybe the devs share the same view. Maybe there are bandwidth technical issues. Maybe there are technical rules the console manufacturers have in place. Maybe it feeds into the dev's paranoia that it would be used 99% of the time for harassment. Who knows at this point.

But from my perspective, they should put one in anyway. It would provide the game with a consistent baseline VoIP that could unite all current and future platform support, instead of console players reaching for their smartphone app or the console's party chat.

Maybe the quality won't be as good as the third party VoIPs are nowadays, but it certainly wouldn't hurt.

Might be a good idea to add it to the Q&A live letter thread they have going on at the moment. They are gathering potential questions to ask the devs.
