That's because game is evolving. Obvious high-top tiers like Geras/Erron/Sonya/Jaqui were recognized much faster.I can name you few weakness of her right away. Just 1 viable KB, her FB sucks hard. Even when on combo you can miss her FB, SonicFox missed one.
KB and FB are a huge advantage and match decider in a lot of case.

They maybe a people that were saying she is top tier in the begining, but that was pretty minor, compare to people that think she was "garbage".
I dont see anything broken in her, instead i see almost perfectly balanced character.
And i do think she had bad match ups.
Probably "nobody" cared about Cassie competitively except few people (Gross/Foxy).
And they are playing with different char now.
