Hello,
I completely agree with turning dead talk on. I constantly hear individuals moan about long spawn times being the concern in order to continue destroying a small enemy base. I believe dead talk would encourage them to talk to their teammates and inform them of the location, so that someone else could continue the attack. Another thing I see is how frightened individuals are of moving forward. Dead talk would allow dead players to inform their teams of certain areas being clear and give the teams the opportunity to move forward and improve chances of success, because honestly, isn't that what gaming is about, winning?
