I think the best option for her combos that don't spend meter, ex: b231xx low fan is to walk back a bit and toss a straight fan.
This will cover most options. In particular, jump ins since we can now convert for 20% off of it if they do disrespect the +9 on hit.
Only In the corner can we check with normals.
You might be wondering why not walk back fan nado and that's because it is inconsistent. Most of the time you get players who will jump, and in most cases, they go right over the fannado.
Of course, you can walk back and see how they respond; our s1 has a higher hitbox above it so we can easily snipe jump ins, especially neutral jumps.
