In games like Destiny or CS:GO for example, you should not even be allowed to start the activity without a working microphone. I dont care if you are antisocial, if that’s the case, those activaties aren’t for you and you shouldn’t bring down your entire team because of that.
As an clarification, I’m more worried about Raids than PVP
Destiny raids, but another is FFXIV, I did Omega awhile back and that is impossible without communication
