I don't know if it's broken or if it doesn't exist but pinging on a PC is just silent. I've already set all my volume to max. It's not much but it'd be a bit easier when a party member pings for whatever reason and we could actually hear the ping sound without having to look at the map every 5 seconds to check if someone is pinging.

Maybe a pinging icon beside the name/avatar of the moron spamming along with a mute option xD
