dash has improved dramatically, I don't know where your getting her being the exact same. Yes she may still act like she's all that, but that's in her character. Hell, it's one of her defining traits. I don't WANT them to take it away. And like I said, she has developed. she's become more caring, less selfish, and much more empathetic then when she started. Same with all of the mane 6, they're all much better then when they started their adventures. Except maybe fluttershy... But still, they've all developed a lot.
