Conclave has a new way to find a group, which beats out anything you'll find here. At the Adventurer's Hall, you can list your party as looking for new members, or browse the listings of other parties and join one that you like. You can see the names, portraits, levels, and archetypes of the members of other parties, see what time zone they play in, find out how often they play, and see if they've any comments they've left about themselves.
To reach the Adventurer's Hall, just click the "Find a Party" button in the column under your character portrait, as seen during quest selection or while on a quest. As always, players can join parties mid-quest, so no need to wait until you get back home to flesh out your party!
