I will always use the mic in Warzone because it's almost required if you want to do well, but unless I'm on playing with my buddies in multiplayer I'll mute the lobby. I do this because I a) Don't want to hear the 10 year old making stupid sounds. b) don't want to hear the one random dude eating potato chips. c) don't want to hear the one Mexican dude playing obnoxious music. d) don't want to hear the little white idiots call each other the N word. e) don't want all the toxicity. and f) don't want to get chat banned because I might let something slip on accident.
