The new season

I just saw a clip from season 7 on facebook. It featured Celestia and Twilight sitting at a table together. Twilight is talking about how Celestia sent her to ponyville and realising it's time for her to send Starlight away too.

I really don't know what to think about this.

Celestia only sent Twilight to Ponyville to help prepare for the summer sun celebration. It was Twilight who decided to stay with her friends.

But this scene seems to be trying to imply that sending your students away is some kind of tradition among.

Also Twilight was Celestia's student for years before she left. Why is it now that she has to send Starlight away? Are the writers sick of writing her and this is supposed to be a way of getting rid of her?

I think I'm starting to fall out of love with the show... But I still love the characters and Equestria. I'm not going to make any firm decisions yet and I'm going to keep looking forward to the new season. But if I come to a point where I'm only just keeping up with the show and sticking to fan fiction for my pony fix, then so be it. I'm ready.
