Is it a mistake to skip Robin a second time?

I wasn’t playing during her first banner, and I skipped her first rerun in 2.5 for Black Swan and Kafka, as Black Swan is my favorite character and Kafka just happens to be her best teammate.

I didn’t really see a problem with it, and told myself that I would just get her on her next rerun. Now that her next rerun is in a month, I feel obligated to pull for her, and I even started prefarming for her. But after all the f2p E0S0 showcases and the cool trailers, I find that I want The Herta quite a bit more than Robin.

I feel like it would be a waste of stamina if I don’t get Robin, and the fact that Ruan Mei is my only harmony character doesn’t help. And after 3.0, I was planning on getting Jiaoqiu instead of Tribbie (I feel like he might be in 3.1), so if I skip Robin, I won’t be getting another harmony unit for a while.
