The only times I've ever used a microphone in multiplayer was with a few friends on Battlefield, and that was it. When they weren't on, I didn't talk with anybody. I've never talked with anybody on Destiny, yet in both games there was still team play and we could still pull off the objectives. The entire argument that the only way to succeed is to have a microphone is rubbish. A microphone doesn't make a random (and someone picked up on an LFG site is still a random, thus no different from someone you are match made with) any less of an asshole or a bad player. The only difference is you can hear them. I've played with plenty of solid players in match made modes with no talking. In the three times I've run a raid, the one time that I completed it was without saying a single word to anyone. On the other occasions I was booted without reason (like dying after everyone else) or simply joining to assist. I haven't played another raid since because I haven't the time or patience to do what the game should be doing for me, only to have my time wasted when the people I link up with are either incapable or boot you for stupid reasons. At least with a matchmaking system, I could quickly locate another group.
