Agreed, you don't need a mic if you bring minimal skill. You see when people die. After the first run, you know the tactics - which aren't that diffucult to understand "don't stand in the green glowing pools", "position yourself on the portal plates" and all the rest ... Are just the same in most games. When you need to form groups at Atheon, those groups should have already formed partially by defeating the other stages - and to clarify things you can always shoot people in the head and afterwards to the place they should go, point etc.. If they aren't dumb, they will understand you. "You need a mic otherwise you can't raid". If you are stupid as hell maybe. Just the same as people say "you need a mic" in wow arena pvp ... You don't.
