I think CR ruined the communications that you're talking about.
It isn't just how people communicated in groups during the dungeons, it's how people communicated in general on the server.
Sure there were assholes, but as it is in real life; if you have a particular skill and no one else is available, we're forced to go with the asshole and that was part of the spirit. The ninja looting, no skills assholes you could shame out in /2 and I liked that too. Your name and reputation meant something and you could become someone if you put in the time. I'm not saying everyone knew everyone and assholes didn't exist because we brought them to justice, but I felt that there was a general consensus that you had to play with these people or start over, so better get the best of it.
