I really want to play this game to it's fullest, which means elite/nightmare dungeons as well, though i've only managed to get one friend into the game so far(he loved it obviously) and it feels like nightmare dungeons need 5 people on vent/skype to do D:
Same goes for raids.
So, to ask a question. How are the "cabals" ingame? Have you had any good nightmare experiences with pugs? And how "dedicated" are the community to actually doing nightmare mode dungeons?
