Spoilers vs Ayane: Haven't been playing much as of late. I've started back on PS3. But Ayane is the most annoying match-up I could find 64H messes up her pressure game in terms of mids along with the vortex she has after it. Kasumi also have the vortex, but off the 236T, 1T, 46H is when the vortex is effective. Ayane's hold makes it that much harder to pressure her with mids, making her change up her game that much more against her.
Edit: I take the fact that Ayane has to guess 64H in order to get it along with Kasumi's other tools & ways to pressure around the hold & tools like 4H+K, H+K, & her kicks on starter to keep it as a 5-5, but the hold is something to fear. I look at it that way instead.
I had mixed feelings on Lei Fang, Akira & Sarah but figured it out. While Akira & Lei Fang have very sick parries to shut down her game & safer, it doesn't change the fact she's still a character that can make decisive moves in order to win the match. Not to mention she has parries of her own to her disposal that shuts down their jabs.
Spoiler vs Ryu: Kasumi has the quick attacks with the poke & punches but Busa has the holds & the izunas & the space. Master agrees with the number.
Edit:
Bushido Kasumi vs Kokoro is an even match. Off the start Kasumi gets her with the speed game, but once Kokoro spaces her, it's fairly harder for her to get in.
