Almost all games come with a day one patch, it's very possible that the game needs the patch to work correctly. Or the online is just.. you know... shit.
My hope is that they lowered the hit box on the kick portion of PPK. She needs a string for basic launch height, PPP the last hit comes out too slow and 236 PKP needs additional height to land.
If that guarantees a force tech that'll be nice, not sure if Ayane just failed to get up. Also Helena should be able to CB from that string seeing as it does... 5 hits(?)
