Going on from what I've said earlier, I have to emphasise the bizarreness of being able to flirt with Satele Shan and Empress Acina while not being able to do so with characters our characters are much closer to. SWTOR, post-vanilla, has been really good at always giving me an option that feels in-character for whoever I'm roleplaying given the setting concepts - right up until I ran into Vette and didn't get a flirt option. Since I got that popup letting me flirt with Kaliyo back in Anarchy In Paradise I've been desperately holding out hope for more companions to have that, but with Vette and Aric having gone past without one coming up, it seems like this has been forgotten.
I'm loathe to use emotional language here, but the idea of not having that option honestly scares me. I've become so invested in these characters at this point that the idea of being locked out of even EXPRESSING romantic attraction feels uncharacteristically regressive. While I was sad about Cassandra in DA:I, for example, not being interested in me - at least I was able to ask her out, act as MY character would. Is Jaesa going to be interested in my Sith Warrior? Probably not, for much the same reasons as she wouldn't be interested in a relationship with a male one. But I want to be able to play that out.
Ultimately I've become much more invested in the idea of these formerly gender-locked romances becoming available than perhaps I should be, but...
When I first played SWTOR, when it launched, I had a few characters which I played to the end of Chapter 1 or 2. A bounty hunter, an inquisitor, and an imperial agent. All three had only one romance option at the time - and so, in the interest of seeing the story, I chose to initiate a romance with that partner.
A few years later, I returned to the game, beginning to play those characters again. I had realised, in that time, that I was only romantically attracted to women. I was, ingame, unable to break off those relationships, which varied from frustrating (Andronikos Revel talking about sharing his bunk with a Sith, even after I'd repeatedly stated my disinterest) to horrifying (Vector Hyllz initiates the implied sex scene without any option to refuse from the player - perhaps in-character given his recruitment mission is entirely about the lack of consent, nonetheless horrifying). My Inquisitor would go on to romance Lana, and that felt like a natural match - but my companions have always been, and will continue to be, one of the main reasons I play Bioware games. You are incredible writers and voice actors, and you have done an amazing job at bringing these characters to life. And as a result, I've been unwilling to start Knights of the Fallen Empire on any other characters - losing them would take away much of the reason I play the game, after all.
This is why I ask for more companions to be romancible, regardless of player class or gender - for replay value, for reasons to go through that story arc again, for the chance to do what we could not originally, for the chance to tell a story that WASN'T an option at first.
Please, Bioware. Do what you couldn't at launch, because of technology, because of LucasArt's constraints, because of the political climate. Make love free.
