Yea this would be really helpful for the new trainers on the server and I think in the evolution stones page they should add that mm is only available for 1 use at a time.
The trainer book's needed an update for a while now. This guide really covers most of the things that need to be added/updated in the book.
With the new update there would also need to be a page explaining trainer npcs as well. I don't think listing them individually would be needed though. Thanks for the comments guys!
