The idea of playing in a PUG -- or a random pick up group -- was once a painful one. You might spend ages in chat trying to find random players willing to join you for a dungeon only to get stuck spending hours trying to successfully navigate the dungeon... or even longer if you were unlucky enough to be trying to run Blackrock Depths. Grouping could be painful, which meant you tended to stick with guildmates or friends for dungeon runs that wouldn't leave you wanting to tear your hair out.
Of course, in today's game, the dungeon finder and raid finder make getting groups together a simple task, and dungeon running itself has been streamlined to make it easier for random groups to succeed. With these changes, it's gotten a lot easier to run a random dungeon, and so some of the stigma around PUGs seems to have faded -- or perhaps just transferred to LFRs.
For today's discussion, I'm wondering: do you play WoW in random groups? Or do you rather stick with guildmates and friends?
