Unfortunately, there isn't a lot to do while waiting to get in a group for a dungeon. There's no crafting, no player-versus-player combat, no random monsters to beat up, and no auction house. This is true to D&D -- I won't deny that. But in an MMO environment, it can lead to a lot of thumb twiddling. There really is nothing to do. You can turn in some dungeon drops to collectors (more on that in a minute), repair your gear, sell your spoils of war to a vendor, and look for more quests. Other than that, there isn't really any actual game to play. You can't go into a dungeon on your own, unless it's small and you're at least one level above the requirement. But in this situation, it's over quickly and you don't get a lot of experience points. D&D's party- and dungeon-oriented system just doesn't slide smoothly into the MMO model.
