That's the best part man, hearing how someone banged your mother, or calls you every racist name in the book or uses a pitch shifter for their voice. HAHAHA, that's why I like private party chats. You can only hear your team and that's it. It's really cut down on the amount of back and forth banter. Which honestly, used to be a blast. Back when MW3 introduced the rage chat. You could hear your enemy rage for a second or two after killing them. I loved that in the game. I believe it's still there in the COD's but ever since I moved to the PS4, I don't do the open chat with lobbies anymore.
