Indeed, but the tome gear is essentially almost as goo as raid gear isn't it? I guess I should have been more specific and said that the dungeons would appear to be balanced for the best gear available in the MSQ without using Tomes or raiding. But I do understand your point, and anyone who has been playing for a while will have at least some tome gear. even so, I think the dungeons are balanced to a lowest common denominator, aka whatever the best from MSQ is.
