By bb.f+B do you mean backdash against jump ins and try to nail them with her f+B? Also is her qcb+B in the air safe on block?
Also, just for the record, does she have any other cross ups?
When you do air command attacks, in most cases they actually make you backdash farther, that's why you use it.
On a side note, if you notice an opponent not retaliating or using down B after a air qcb+B, you can just spam several times in a row. Krazykone, I see that you put the shortcut as d, db, b, ub+B, which is how you should do all air shortcuts but since that does a back jump, I usually do a near 360 motion like this for forward jump uf, f, df, d, db, b+B.
