You know ,years ago i was trying to do the same thing in fighting games untill a very good player i know told me this: "You know there is no reason to try to low/high crash all the time,Why don't you just block like normal people do?"
~Wise advice here!
So just block low(or learn to brake...
after an A+B knd u have a lot of options....
not ukemi traps but anyway.
66B/66_throw
DB_B/A/K/throw
WR_K/B/A/throw
214~PO options
2A+B(note that it can be interupted or avoided with jumpor back ukemi)
11A/44A
It was a question of self realization and quest for insight thinking for you.... but anyway.
Because for me she only lost some extra damage, the oki game is still there just in different way and more "straight"(sorry english is not my 1st language).
