You absolutely need to implement qcf+1 and qcf+2,1 as well as the judgment stance with Anna. It's really not that hard. All of Anna's qcf attacks have shortcuts.
After you do pretty much any launcher with her, follow up with down/forward+3,2. After this move, do not take your hands off of d/f. Keep d/f held with your thumb. She will do a dash and you simply press 1 to do the qcf attack. Then forward+3,2 for then bound. Then qcf+2,1 as combo ender.
Also, a lot of her moves can be cancelled into judgment stance. I can do practice session sometime if you'd like.
And Nina's u/f+3 on normal hit doesn't combo. But when you interrupt an opponent move with u/f+3, you often have the opportunity to follow up with d+4,1 then ivory cutter. It all depends on the opponents position in the air.
