this was suggested on the old forums, and i think ill revive it.
this suggestion is mainly for survival mode.
"spying" is a problem in survival mode and quite annoying. to prevent that, disable chat for dead people, or make it so only spectators and dead people can hear each other. and living people can only hear living people. with this as a server option it would stop people from spying. with no talking dead, survival mode would be a little more "realistic" and more challenging.
