Most of the episodes are pretty weak though, and I didn't love the whole school arc. It had too many characters to create stories for with the new mane 6 students and then bumbled it. It coming right after the movie didnt help things.The entire concept of the school happened within 5 minutes and then BOOM suddenly there is a school. It felt VERY rushed and had it been developed more in the show it might've been better
No, because all her friends are human, and she has become succesful in the human world and is happy there. And the technology she likes in thr human world doesn't exist in Equestria.
Rainbow Daah has to be told to do her job half the time. She couldn't even be bothered to study about a topic she loves (Wonderbolts) for her dream job
I'm guessing she joined the human world right after the previous games had finished, and since Canterlot lost badly and hated the games, no one wanted to talk about it there.
She's probably tell them it's too dangerous. The only reason she took Starlight is because of her friendship with Twilight, so she knew Starlight was trustworthy.
