I was just saying she wasn't braindead and you're just listing all her strengths, so let's go through what you said because I love dissecting people's salt with actual truth.
Great mixup options? All of her lows are slow as hell. B1=18 frames startup and if you finish the string it'd punishable on block. F3 19 frames start-up. Everyone blocks low and if you see F4 coming you can block the overhead.
She has amazing staggers yes, one is advancing the other is a 9 frame mid that's 0 on block. This makes her S tier.
Overhead fatal blow that's also slow as hell and all it takes it to block standing cause the chances they'll use it in a combo is slim to none since it's distance based, using it in a combo is pretty hard to do.
Safe strings with pushback?
B243 is not SAFE, 3 is a high and can be ducked and punished
F2 1+3, the F2 is a high and can be ducked and punished
F343, the last 3 has a HUGE gap.
111 is safe, but can be poked.
Every heard of whiff punishing? You can catch her with this tactic, like with any other character. Try playing neutral more and labbing her and you'll beat her.
