Non-Casting Classes are therefore Warrior, Wilderness and Subterfuge.
What should these classes do?
Warriors should be the best at combat, because they don't have subspecialisations, but the other two need to be good at particular areas of combat. Wilderness types should be much better than warriors at archery, and not bad at skirmishing. Subterfuge types should be able to do massive damage when they get up close and personal (and behind you), but also be much, much more vulnerable to having damage done to them.
Wilderness should also be doing alchemist fuelling / emergency herbal healing, tracking/awareness, and stealth. They should be between Warrior and Rogue in how hard they are (this is currently achieved by Fur and Leather Hardening).
Subterfugers should also have skills for shedding accountability, hiding things about their person, using poisons, picking pockets (and planting things), and stealth. They might also have some urban tracking and some Win In Downtime skills.
