I hate Rachael already. Went into the lab to see her frames, since my training partners are beating me pretty bad with her, and she has ~5(approximation from memory since not at home) unsafe moves out of ~72 moves........let that sink in......~5 unsafe moves! She can sort of be punished, but that is if you're playing Kasumi would you be able to do it reliably. Not to mention her speed and reach coupled with her above average damage. She is going to be a VERY hard character to deal with.
ALTHOUGH, I did notice that a lot of her moves leave her ~ -2 to -5. She can be grab punished if timed correctly. And a majority of her moves hit mid, so make those reads!
