Bring back Auto-walk while chatting

I can't think of any good reasons why you shouldn't be able to chat while auto-walking..
It especially sucks when you are running away and you want to inform your group about danger or ask for help. Not all people like to be in a VC all the time and chatting generally has it consequences, either if you run against a tree and get stuck or make a sound and revealing your location.

Please bring it back, or tell us at least why it shouldn't be possible
