Also, as a general rule, most "high end" duties are run via the party finder, not the duty finder. For most of them if you were to just que, you could sit there for a week or more and never see a pop. And even if a group did form, you would likely watch the group fail because they werent ready and quickly disband. Party Finder lets you pre-form a group for any duty in the game(including chatting with the party members as the group fills), as well as search which groups are currently open to see if any meet your needs.
