Yes you're correctThose are nice combos, but only problem is B3 is hard to land after the F23 so it not something that could be done constantly. It also does not work on character with small hitboxes like Batgirl, Hawkgirl, etc. As well for the 3~rising grab is also hard to land midscreen.
Again good combos, just not something that someone can land on the constant basis. I do love the meterless combo that deals 52% that only requires trait. That is sick!
Small hitboxs are problamatic:
Out Of all characters batgirl, hawkgirl, harley, KF, CW, Raven and NW and GA drop out after f23, b3
Everybody else to my knowledge is vulnerable.
