If by a feature you mean we get to hear overly obnoxious idiots taking bong hoots and then coughing into their mic for 20 mins straight then yes, we got a feature they don't have.
Of course you can leave the channel... but it has to be done every single time you login. Most of the time is no issue... it just sucks walking into a place and then all of a sudden you hear screaming kids, people doing drugs, people fighting - or one of my other favourites "can anybody craft this - hellllooooo, is anybody there, I need this crafted."
So glad we have text chat now because it's eliminated this problem by alot. Since PS4 has party chat, we don't need in-game voice chat, it's nothing but a nuisance.
