I would agree, but she is getting stunned left and right. Looks like you may need to equip her with the two 50% stun resist prints (Trove of Knowledge and Saintly Delivery) to get any use out of the S2, let alone get through the fight.
Granted, I've only done it on Standard, but I equipped a Fjorm with Indelible Summer (and Heralds of Hinomoto).
