'Mentor' Pack Role

So I was feeding my adolescent wolves today and it hit me that regardless of their older age, they're virtually no different than pups. They can't hunt, scout, pupsit, or be herbalists; the only distinction is that they no longer need to be pupsat. It makes sense that pups can't do these things, but adolescence is a period of preparation for adult life. I really think that they should be able to contribute to their packs in some capacity, even if its very reduced. More than anything, I want raising adolescents to feel worth the effort, and this is where my idea for the Mentor pack role came from.

A Mentor would be an adult wolf with the job of training an adolescent in a given pack role, increasing their student's proficiency before they even reach adulthood. Their aptitude at this would be influenced by two factors: first, their existing proficiency in the skill being taught; and second, their proficiency at Mentorship.

This split proficiency system means that in order for the Mentor role to be worth utilizing, a player would need to have invested in a Mentor wolf's other skill proficiencies beforehand. A wolf who is skilled in Mentorship but with no experience in their taught skill would be a very ineffective teacher. Mentorship proficiency could gradually increase after each teaching session. 

I have a few other ideas for balancing this role so it wouldn't make the game significantly easier:

• Implement a cap for individual mentoring sessions per day, similarly to how hunters can only participate in 10 daily hunts. A limit of 5 or less per rollover seems reasonable.
• Implement a significant energy cost. Each mentoring session would use up all of the Mentor's energy (like with Scouting sessions for Scouts). 
• Poor personality synergy between a Mentor and adolescent could negatively impact the latter's proficiency growth. This would force players to strategically pair up their duos.
• By nature, the Mentor role is mutually exclusive with other pack roles; yet to be effective, Mentors would need to be proficient in another role beforehand. Consequently, a player would have to seriously consider whether the costs of making a useful wolf into a Mentor would be worth the potential benefits. 
• Slow proficiency growth. I'm unsure what the current rate of proficiency growth is for each adult pack role, but skill growth gained by adolescents could be 3/4 or 1/2 of the adult rate. 

Despite the heavy drawbacks, the benefits of the Mentor role are obvious. Adult wolves who were mentored as adolescents would have an edge over their peers due to their extra role proficiency. 

Feel free to suggest tweaks or offer criticism! I'm by no means an expert on game design or implementation, lol.

Have a great day :)

EDIT: I should have looked more closely at the suggestion masterpost, as something similar has already been suggested! My apologies for cluttering the board.
