With better direction and a bit of vision Arona could have had quite a good character arc, though. I don't know how her dom self reacts, but by the scene in the baths it's pretty clear Sub Arona is bothered by how people view her and does kind of understand where the problem lies, so in my opinion it would have been a great spot to put a variable in place and then have it trigger during the cow teacher quest.
If Arona_Talk_Bath=False (or whatever) then she gets halted, the Champion and Brienne look down on her as they do, and she stomps away like she does.
If Arona_Talk_Bath=True then maybe she plays it a bit more sympathetic, perhaps the Champion and Brienne help her out, 'cause y'know the Champion did just confess their love for her and Brienne did just have a front row seat for that whole heart-to-heart, and thus she ends up being allowed into the classroom and is actually given the chance to improve relations between orcs and minos/showcase that she's not just some raping orc.
Like, i don't know. Maybe you could even restrict it to Sub Arona, although i don't really think even Dom Arona is that bad by CoC standards considering her just-met self eventually lets the Champion go if they lose to her (as opposed to the foxes who get a bad ending) and that the orcs at large actually do quit the pillaging and raiding after their issues are solved (as opposed to the foxes/marefolk who just keep going around bending over people).
But either way i think it would've been nice, pretty cool 'cause reactionary, and would have served better thematically to boot (union over division, which is really what the effort to fight Kaz is all about).
