The Hall of the Novice could do with some updates, but I see no reason of benefit to making it mandatory. It will just be done and forgotten by new players while becoming an annoying chore for other players on new characters. New players will need more than a 1 time session to learn how to play properly, especially if that learning session happens before they have any dungeon experience that could be used to put the lessons in context. Something more beneficial might be a new roulette for mentors (with no rewards at all) that pairs them with new players running the low level dungeons. Perhaps the Novice Hall sessions could also be expanded to let a mentor player watch over them and provide live help to a novice working through the training.
