You want to know why I think Ymir is worth more than Sasha to the story? Because Ymir was used correctly. Isayama knew when to make use of her, and he knew exactly when he no longer needed her for the story. Ymir was a plot device, plain and simple, and her purpose was to elevate Historia in the narrative. And if Historia knows, or comes to find out in the future, that Galliard ate Ymir, then I have a feeling that Ymir will continue to play a posthumous role as a motivator for Historia to try to avenge her. I can't say anything like that about Sasha.

I don't think there was anything else to be done with Ymir. She served her narrative purpose, and she did it well. And beyond that, she felt like a legitimate addition to the main cast, and her interplay with other members of the 104th in the Clash of the Titans arc is some of my favorite in the series. She had clear, defined ties to the other characters, and she had relationships with people besides Historia (the most apparent ones being Reiner and Connie). Ymir was a character with a clear purpose in the overall story; giving Historia the confidence to reject her past and forge her own way in life. And not only did she accomplish that goal, but she was able to make a name for herself in the fandom due to how good her writing was, and she had the good grace (and Isayama the good sense) to bow out once her arc and her role was completed, ensuring that she would not overstay her welcome and be subjected to the same predicament that Sasha found herself in for almost 70 chapters.
