In my experience yeah, it was better before the systems went cross realm. Before that, you lived on your reputation: you treated people with respect you were treated back with respect. You were an idiot to other people you risked yourself to be blacklisted on a server level.
While I understand the need for cross realm systems, it is true that it killed the sense of community withing the game. Nowadays people usually join and leave groups without a simple hi/bye.
