Other than her face and the tie fighter just sitting there in her egent, there doesn't seem to be much talk about her.
She seems like one of the more useful Phoenix toons outside of a Phoenix squad. She basically has a Leia style basic, and her specials are pretty good too. She also has pretty good base speed.
To me, she is the best Phoenix toon. I like Zeb and Ezra too, but Sabine is easily my favorite.
