Villainous literally has said everything I've pretty much stumbled upon in these few days of playing.
Granted, she's pretty unsafe, but she has quite the mixup game, and she does good damage (not amazing, but good, even if you play conservative and don't use a lot of meter.)
I use 4A+B most of the time to seperate the orb from me now. At a distance, it's not horribly punishable since she can block before the animation finishes. My opponents are too accustomed to 6A+B(though I can use it from a distance), AAB and BBB now for me to use them all that much. I've been getting punished regularly for the highs. :\
As Villainous said, 8A+B is just...stupid. I daresay it's her best move. It techcrouches, the orb semi-tracks, it rings out, and it does good damage. I really can't say enough good things about this move.
I still wish we had a really good low though. I guess decent damage off of CH 1A and good damage off of 1A+B is nothing to gripe about, haha.
