The school is a stupid idea, but that's what we were given. Hopefully we'll get to see as little of it as possible, but from the leaked synopses, it's going to be prominent.
It sucks, I wish we had more episodes that arise from everyday situations, something more slice of life. Instead, we get the cutie map and school/student related conflicts.
I miss the simpler premises of "be caught in a storm", "get a too big commission", "try to get a contract with a famous photographer" instead of "two ponies in Canterlot are arguing, go save their business", "make AJ a judge in your fashion competition and let her ruin everything", etc.
It's what separates It Isn't the Mane Thing from Spice Up Your Life, Canterlot Boutique from Inspiration Manifestation, etc.
To be fair, Rarity got the better side of the stick, but overall it's a different story.
And now we're not getting a Rarity episode at all in S8, and only two where she's paired with someone. S7 was already missing Rarity in half its episodes, I don't want this trend to continue. Shifting the focus from the M6 is ass, but Rara not getting her fair slice is painful.
