So I've been looking at basically every analysis I could find for Three Houses because I literally cannot wait for it and noticed that no one really seems to have a good idea to what the three stars mean on the 1 on 1 tutoring screen. While the arrows up and down were pretty explicit, the three stars didn't seem to stand out. After a while though, I just happened to think about the formations and how we have seen footsoldiers, mages, mounted units, and archers. What if the three stars are representing the type of soldiers your battalion currently uses? In the trailer, Dorothea is the only one to not have formations symbols and the three stars are under "Reason" with an E rank. Perhaps battalions are tied the ranks, unlocked by them, enhanced by them, or some combination? No real evidence to support it either way but wondered what others thought all the same.
