Without a doubt, Astaroth is her worst matchup. At the moment, it's the only match I REALLY struggle with.
Leixia and NM also can be trouble, but I can generally handle them. But a good Astaroth doesn't just feel like an uphill battle, it feels like a CLIFF.
I know a bit about leixa. Gnouzcalibur made a "leixia must die" video. Idk if it was posted. Its in french but they give you the visual. I guess it will be the first match up to discuss.
