I have always found OG gun sounds to be obnoxious at best and i remember there being the option to replace it with a custom sound. Given they changed the way the folders are is this possible with classic? if so how would one do this?
I used to have an addon called Gun Silencer that worked. It changed a sound file so all gunshots, even from other players, made a better sound effect.
Not tried to look for Classic version, yet.
