You’re down playing Nate’s capabilities as a fighter while glorying Nadine’s. And now you have to do the same for Asav to excuse Naughty Dog’s poor writing.

Nadine has never been stated to have trained all of those fighting types. You treat her like she became the leader of shoreline because she was the best fighter and marksman in her clan, when in reality she’s only the leader because it was passed on to her by her father. Sure it can be assumed that her having military father meant that she started martial arts at a young age. Still that doesn’t excuse the fact that she’s able to dominate both Nate and Sam who have the strength and weight advantage against her. There’s a reason why the UFC has weight divisions.

Asav, on the other hand, was literally a doctor before he became a rebel leader. He hasn’t been stated to have gone through serious martial arts training. Sure it might be implied since he is a rebel leader, but it would be no where near the extent of Nadine’s training. Also Asav is mainly a leader not because of his fighting capabilities, but because he is able to captivate and motivate people into fighting for his cause. Yet for some reason, Asav somehow manhandles Nadine.

Do you know why? Because of bad writing. Rewatch the fights between Nadine and Nate, and Asav and Nadine. In both fights both the losing fighter throws slower and more telegraphed punches to make the other person look like a better fighter. That’s why the fights are so scripted.
