Even if I liked the Student Six, especially their color pallete together, I was always more interested in the idea of the Mane Six and the school’s relationship.
I always felt like there should have had more times that the Mane Six taught the kids a moral lesson. It’s okay for the Mane Six to mess up, sometimes adults can be out of touch with young crowd, but I think this was a good oppurtunity to show how the Mane Six matured. I’m looking at you AJ and RD! It’s like if your Sunday School teachers are teaching you about not being jealous when you youself are very jealous.
And honestly maybe only Twilight, Fluttershy and Starlight should have taught in the school. I just don’t see Rainbow as a good teacher.
Getting back to the Student Six, maybe they should have had a lesser amount to have more focus on certain ones. At the very least there should be some focus on how the Mane Six positively influenced those rascals.
