Although its not gonna make the game I am pleased with this if its happens. 3 arc actually goes a tad bit forward with the games they make like objective leader boards ect then IW went backwards by not using their ideas.
Nice to hear about a new feature. Little things like this just show the though Treyarch put into their titles. I can't see any problem with new menu features.
TBH why dont they just do it like it is in BF3, like only have Chat between Squad or Team, so basically before your even in the Game it already knows to mute everyone else. TBH it don't bother me anyway always in Party or Private Chat when playing CoD or any game TBH!
