I'm on Last Round Core Fighters right now. I'll have notes up by tomorrow or Monday.
But a few things;
6P on BT opponents is +24 (+16 at faster stagger), 6P3 is +27, 6P3[4] is +22. 6PP is a guaranteed launch. You cannot stagger it or hold it, at all. This is going to create loads of mix up. You cannot stagger or block follow ups from 6P3 when you get hit from behind, at all. I'm going to create so much vortex off of this.
3K does not stun on BT opponents at all anymore, it is only +1 now. 3KK can be held due to lack of stun. However, you cannot block 3KK, so it is still a decent mix up.
236H+K refloat doesn't seem to give Ayane much to work with for juggles, trying some things after the 46H mid k hold. Not racking up much.
Also, Ayane does not have any new moves. The increase into the movelist is just listing things that were not listed in her command list in Vanilla or 5U (which is exactly what I thought would happen).
