With the dicussion of pets, I would really enjoy animal trianing still being a ranger area of involvment. Instructing pets to perform certain actions and be able to do certain thing to me would still be a niche rangers could control. Also can see it as being a way to learn animal lore and teaching for rangers in the future.
