You can rest ur brothers already? Just dont move and you gained 15 fatigue.I dont see what your suggestions would add to the game.
Thats the reason why we decided not to implement any extra fatigue regain.
The basic regain already covers the “resting”. Not spending AP improves fatigue regain, because if you dont spend any fatigue you recover more.
For example: by NOT moving one tile your fatigue regeneration is improved by +2.
