She shouldn’t have been able to do ANYTHING to stop him or slow him down. Honestly be shouldn’t have even been involved at this level of getting his hands dirty. Instead of a Kate/Fisk fight I’d have rather seen a Kate/Elenor fight, with her mom using a sword. Keep Kingpin as the Kingpin - pulling the strings but not directly involved at this point, and give that fight more drama with us actually seeing Elenor’s skills.
Another Kingpin related thing, in that fight with Maya and dude who betrayed her, I would have liked to see him commit suicide out of fear of Kingpin instead of her killing him, again just to boost how terrifying Fisk is…
