I think the dungeons, that you can queue up with other players, is so much fun during leveling. It’s tiers better than the standard fetch quest where you are just literally running back in forth in town talking to the same two people over and over.
I’d love to see more dungeons for leveling purposes. Maybe even an ability to just queue up for dungeons in every zone you enter to bypass the quest system.
I don’t mind some questing, but definitely prefer to do the dungeons.
