You can break 10k now if you fought Haku or Tager.
Nah if anything it might finally be even for Tager.
As for iad back j.C, I have a set up with 5B jump cancel so that you forward jump over them, iad back then wait till you start descending and turn around to hit j.C. When done right you should be able to confirm into dash 5B and follow up however you want.
Tsubaki, On the other hand I whole heartily suggest counter picking Tao in CSEX, maybe Carl as well.
Good point, so 214A~C~A > dash 2A probably doesn't work as well. =/
