I don't like to leave my mic open, and I'd like to turn my mic on only when needed. I don't like Push-to-talk, because then if I'm in the middle of a fight, i probably have to stop engaging so I can push the mic button. I could put it on my mouse, but I've already prioritized the 7 buttons on my mouse for other actions that I think are more important. It would be great to have an option to select how the mic works, either Toggle Mic On/Off, or PTT, and then select the key bind for that. Then I can turn the mic off quickly when I'm in an event I don't need to talk in, and turn it on when I'm in a strike or Crucible or something else that requires communication. Other games like Overwatch do this, so it's not a new idea.
