I believe that they have intentionally over nerfed her on purpose. There was a saying once I liked and it said "It is easier to tone something down, than it is to ramp up" meaning if they over nerf her and slowly remove nerfs, it will end up being easier (and by extension, better) than by slowly adding nerfs.
I agree that these changes are over the top, but here is hoping it is just as I purposed above.
Specifically I am concerned with her game as it relies on corner and Okizeme strategies more than it does zoning from long range so if they intend for her to be more like that, she would need more new moves than a ranged Distortion drive.
