I may be biased since ive been playing her since she got introduced, but I've never once felt like she lacked to the tools to be viable (great priority, versatile throw game, multiple skip neutral moves, multitude of safe and + gaurd breaks despite her priority, etc), that said I don't think she's top, but she's definitely not struggling, i'd say shes in "strong but not scary" tier, which is like what, mid? high mid?
