Is there an argument against making it easier to help DMs avoid classic mistakes?
I would certainly argue that it is really hard for a book to efficiently do a good job of all of: teaching beginners, teaching folks just past the beginner stage, and being a useful reference to advanced users. And I would further argue that an expensive book is often a poor choice to teach beginners, especially given all of the other tools available.
On the other side, I certainly think that the DMG could certainly be better organized and written, which would make it more friendly and useful to everyone. Beyond that, I think a dozen or score of pages at the beginning explicitly for new DMs would be a great edition.
Except for one or two people who are worried there is nothing to cut to put it in, has anyone come out against putting in a chapter explicitly to help new DMs? Has anyone come out against at least keeping new DMs in mind when reorganizing the DMG?
