I guess that my complaint is that anyone with reasonably solid experience with 3.5E would, on a first read through, pick up around half of the mistakes that are present in a given book. I know that I do, and that's within a day. Are margins so tight in the industry that a few hundred dollars couldn't be spent sitting down an avid gamer or three with a free supply of chips and coke for a day and a new release book? That would also lead to questions that would clarify some PrC special abilities and feats.
