Yes, I'm back with another Class-related question. Don't worry; I looked through all 24 of my Classes and decided to focus on only the ones I can't come up with roles for.
Recap-How Classes Work: In my book, a mysterious pulse of energy sent a young man named John into another world called Alendyias. This event resulted in John becoming Rorjon, a bluish ghost-like being (Kanyeri) that acts as a force of good, guiding, advising, and blessing the people of his new world (Alendyias). One of these blessings was based on John's love of RPGs like DnD, namely Classes. All Classes magically enhance one's potential (capacity), but only within the limits of their held Class. The level of this enhancement increases as the Class-holder grows and gains experience in their Class, and this increase is measured by Levels.
This question is about the Ranger Class, which falls into the Speed and Combat categories. Like all Classes, this Class is almost invariably inherited or granted at birth, magically enhancing the holder's potential. However, this Class's enhancements mostly concern aim, perception, survival skills and adaptiveness.
Rangers are known for their knowledge of nature and their natural gift for surviving. I can see Rangers acting as guides or archers, but in a medieval fantasy society, what other roles would Rangers have? Restated, my question is: What Role Would Rangers Have In a Medieval Fantasy Society?
