It doesn’t matter if I set my game’s volume to an acceptable level if I have a teammate (or more than one) spamming this obstructively loud command. Muting them doesn’t stop their radio messages, either. Yes, it’s possible to type “ignorerad” on console, but that also remove all grenade messages, which means you’ll lose one of the most important communication features there is (that works even if you mute your team of trolls) and you won’t know if grenades you hear popping are from your team or not.
I know this has been said multiple times. Come on, Valve. Save our ears. Besides, there’s no reason for this command to be as loud as it is.
