Me personally, the mic isn't as important as being able to hear whats going on. Especially w/ Kingsfall and def w/ Oryx, so much coordination is required I would think it makes it difficult for a team if someone can't communicate at all. It's a small pain if they can't speak but I've ran raids w/ guys that had the kid sleeping on them or something and it's doable....never done it with someone that had 0 comms.
