I don't think that will do anything. Most I know who played, turned Prox off as soon as they heard another player. I think as long as there is an option to not communicate, people won't. It was the thing that killed me in Crucible...if I wasn't with my friends, communication was non existent. It seems to be a growing trend that people only want to communicate with people they know, even if it's not IRL. I wish this wasn't the case, but it's something I noticed more and more starting with Reach....Co-op campaigns, with nothing but crickets, Firefight that might as well just be score attack, H4 MM, SpOps, Zombies in CoD. I mean, Not even a "Heads" if they accidentally Huck a grenade at ya! It's sad, as I had great times meeting new players back during the early days of Live.... I miss those days.
