Yes I am extremely familiar with her freeze reset and I never said she was bad without vortex, but she would definitely be a lot less scary. I have quite a bit of frost exp thanks to @RunwayMafiaYou do realise she has an inescapable reset right?
I don't see how you could think KF would be bad without her vortex but BG "doesn't need it". Without vortex; BG's meterless damage is meh, her neutral game is weak, her zoning is meh, she can't deal with up close pressure and she becomes just as meter dependent as (if not more than) KF.
Without vortex KF still has; decent oki setups, great meterless damage, great midscreen damage, amazing trait damage, 70%+ inescapable reset, nice corner game, meter dependancy doesn't change, has parry and fast normals to deal with up close pressure and, a strong neutral game with slide, daggers and b1.
Batgirl doesn't have a ton of meterless damage but she has unreactable 50/50s and some seriously strong tools. She gets easy 40% midscreen with 1 bar and her corner game is flat out stupid. I'm sure I'm not as good as you with batgirl but I did main the character so I know what she's capable of, and IMO without her vortex she would still be really good.
