Yes, TOEE is long. Yes, most players like to zerg through it, and it can be done quickly in about 30 mins. or less if you ignore the optionals. But, it also is one of the few quests that you feel like you have really accomplished something when you finish it. Instead of scrapping the whole thing for shorter quests, please do something like you have for Haunted Halls and allow players to enter the "classic" version or the "express" version. There are already tons of short and medium length quests. But TOEE and Haunted Halls are the only two quests you have that are in-depth adventures.
