More drivel because Blizzard cant be wrong.
The game was infinitely more social before LFD and yes you did have to look after your reputation when you were on a server.
The main difference is that getting a group took time and effort and you had to talk to people. People therefore didn't drop group at the first sight of trouble because they knew they would have to get another group and go the effort again. Play on a private server and the difference is huge.
