I'm sure by now many of you have seen people demand that SP complete the books. Many of the books are obviously missing monsters; for example, Good Legion and Evil Legion only have 3 pages. There are female monsters in the game not in the female book.. and so on.
So rather than just sending endless complaints and demands for SP to finish the books, how about taking a different approach, and instead, suggest which monsters should be added to the current book selections.
At the very least, we as a community, will be able to plan ahead at which monsters are worth purchasing if we all agree that a particular monster fits a category. Although we may end up being wrong, and SP has the final word about which monsters actually make it into a book, I think it's a discussion worth having.
TLDR; What I'd like to do on this post is for everyone to discuss exactly which monsters are missing in which book.
