Bring Back Slam For Surf

[Razor]

Voice loopback is able to be toggled by global+ through an exec. However we could make it available to server admins. We changed the voice loopback to off by default because the mic spam was getting out of control. We could change it to default on however, then let server admins change it to off if it gets out of control. Do you think this would be a better solution?
