Good point - Silithus ALWAYS had a low population, because it sucked to get to, and sucked even more to level there. The quests are almost all formulaic, (kill 10 ant monsters, etc.) and there are few plots in any of the quests. Once you hit 60 in the original game, there was plenty to do in _any_ other area that made it worth leaving and never coming back. I did some leveling in all the areas that were available at the time because I liked exploring, but the quests there actively discouraged moving very far from the base, as most of the quests could be completed close by.
