Those are minor things (kind of like little pranks) and not so bad. Ymir is good with Historia for the most part. My main reason for not shipping Historia and Ymir is because of how she is with other people who aren't Historia, like when she even basically said Armin was worthless and not even worth saving, and even basically made Sasha like her maid. Meanwhile, Historia truly is sweet, kind, and caring with just about everyone she can be even with her real personality as Historia, and not just her facade as Krista.

She seemed like she might have started getting better just before she left. Maybe she will be better when she returns. In that case, Historia and Ymir could have a healthy relationship overall. But otherwise, if she's not, that could cause friction in Historia and Ymir's relationship.

Ironically, I also used to have a problem with how Eren treated Mikasa early on, and I felt Mikasa was a bit too good for Eren, but yet I still kind of shipped them, and Eren is better overall now even with Mikasa.
