Not necessarily. She's just looking too good to be safe, there's no way that kicks that fast and mash friendly can be safe....Unless she's linear in how spread out her mix ups are.
I'm not really tbh. She looks like she might be a pain when she gets a stun but if you're patient it'll be hard for her to get it. Her low kicks looked slow from what I remember
And her holds are relatively garbage from what I've seen, they didn't seem to do much damage or give her any major advantages. Her throws aren't bad, but they weren't good either, so there's that too.
I'm not particulary scared of her. Even though her kick strings look unreactable, they seem linear and predictable (all mid K and some high K)
Sure, like all the new characters, people will have trouble fighting her, but with time we'll get used. I remember that before Phase-4 and Honoka were released, they were thought to be "broken" too, but actually they're far from being OP, so we just have to wait and see.
