actually hate to say this but this is a fair point. Practically most fc's doing coil now have a requirement to have access to teamspeak or the like.
PS3/PS4 have the ability to use a chat system in a game and if there was a universal one in game it would bring both platforms together and removing the need for 3rd party chat programs.

however one thing only in dungeons/raids and give the ability to mute or disable mic if you don't want to talk etc.
