So your idea of adventure is bleating in Org trade chat trying to form a group and then taking a long time to fly to X dungeon. I think the loss of 'adventure' or community was lost when cross-realm dungeon queues became a thing. Known douchebags on your server were easy to avoid when you had to manually find groups but it was just potluck with the dungeon queue. But would I want to go back to Vanilla style dungeoning? Not likely, I'd rather do more dungeons with the ease of teleporting to the dungeon and getting into the action instead of waiting around to filter through groups.
