I highly doubt that.
Unless it’s stated she has gotten vastly weaker after massive attacks it shouldn’t be assumed that she lost strength. Even after being
screwed by Psyrochi she was
relatively fine afterwards. Even after being
electrocuted to
death by a weakened Psyrochi, she
seems ok. It’s never mentioned that she lost strength
until she overused her power.
Tatsumaki’s durability is reliant on her barriers so I’m not too sure the BS argument means much, consider she didn’t have a barrier up against them.
Fu should scale to the feat.
