I think that voice chat should be put into Dead by Daylight.
If proximity chat was put into Dead by Daylight I think that it would 1. Help survivors become more coordinated 2. Help killers locate survivors easier 3. Sort've nerf SWF. Currently one of the reasons that SWF is so annoying to go against is they know where you are at every waking moment and have discord calls so they can communicate without you knowing about it. By giving them a way to communicate that can also help you locate them it makes it harder for them to speak without being found and knowing about their plan. So if you play a stealth killer you can learn if they have spine chill because they might exclaim that they do, hear their plans about Wich gens they're going to work on, or help find out if there is anyone around if they start screaming.
