My overall look at the court thing is as follows.
Some particular species have a natural tendancy. Hobs are winter, gruffs are summer, etc. Exceptions will exist (see below).
Many (most?) have no, or only a slight natural prediliction, and their associations and actions will generally determine a court if there is a calling of the wyldfae, but they will generally be left alone.
Many will choose to associate themselves with a court without needing to be born or compelled into one.
