Yeah I won't say it's completely ridiculous since the game isn't that realistic regardless. Though you'd think that those women who are famous for using nagitant will have one rather than a sword (which is likely because the devs haven't programmed that in).There's at least some historical precedent to hang their hat on for that one, women were trained in the use of some weapons to defend the home when the men were away, and there were occasional female samurai like Tomoe Gozen. I'm not aware of the Mongols having any parallel traditions. Also most of the male fighting force on the island just got slaughtered, so upper-class women taking up the family's spare blade and armor would make up a greater percentage of swordbearers than normal.
I'd call the game more of a pastiche of samurai movies than an attempt at a genuine re-creation of the time and place it's set in, so a lot of the "that's not how it would have worked!" complaints don't bother me. And a lot of the characterization and low-affect/exaggerated expressions and speech seem pulled directly from movies.
Dodge has been inconsistent for me as well, sending me flying away from enemies when I wanted to stay close and counterattack.
Upgraded black-powder bombs make some fights that I presume were intended to be pitched battles into jokes. See a crowd of 20 guys? Just lob one and clean up the almost-dead couple of survivors.
I think talking back to samurai is going too far because that's not something I've ever seen in done in japanese media.
Also I want to add two other complaints:
14. The Haiku minigame is shit. Literally the joke of being able to string anything and it will still sound deep.
15. "Don't go zones" that insta-kill you if you try to pass through them.
