TTK had plenty to offer at first. Lots of new quests, new enemies (sort of), a new location... It was fun for a while. It's only after putting in some time, clearing most of your quest log, and reexamining it that you discover what's happened. No reason to feel dumb. Most people, including myself, were pretty happy with it for a while. Until it lost it's newness and we were left with a dumbed down version of the game we used to love.
