I think it would be a good idea for us to come up with a guideline for making fan content to govern using some of the basic rules.
For example, for new characters making equipment lists is always a pain--how to do it? I propose the following:
Refer to the new class as a sub-class, or scion, of one of the basic four classes. That means that they can use all of the equipment like with the basic class, unless otherwise specified by their card. For instance, making a character start with a weapon contrary to their scion indication.
