The main point of daily randoms, in every MMO I'm aware of, is to give people who have already completed a dungeon a reason to go back in for people who haven't completed it. (They let full parties queue because it'd seem weird to people if they couldn't do that.) I hope the designers consider it a mistake to have made the varying quest objectives and drops vary in a way that is so contrary to this. Is this less common with newer dungeons?
