So what? Nobody forced a gun to their head in making the decision that you're the messiah and everyone loves you and you are the best and get pats on your shoulders around every corner.
As for your university circle: Do you want a medal? I really don't know what your point is with bringing that up. I know that there are different sexual orientations and whatnot and haven't argued against it, but that doesn't mean everything has to be represented equally in every game. I'd rather have no hetero romances in the game if that meant the other few romances are better developed and the crew feels more realistic.
"And how do you even justify limiting the amount of roleplay in a roleplaying game"? Well how did BioWare justify continually removing choice and consequences more and more from their games recently? That is way more important to any average roleplayer than 2-3 romances(which are 90% cringeworthy anyways) less.
But it does seem a little like BioWare nowadays prefers pandering in regards to characters aswell as overgratifying the player instead of actually focusing on creating a believeable world with intensive choices and consequences and realistic people in it.
It wouldn't be random civilians. For example you're on some mission in a city hub, meet a thief on the way, help her/him out and you meet them again eventually and things can develop etc. Of course there would have to be enough context as opposed to ME3 Diane Allers who basically had a sign on her head saying "I'm just here for you to have sex with!"
I agree. Why can't things just be friendships nowdays? Everything has to be a romance. I really liked Dorian as a character and saw him as kind of a "bro", then again there were constantly the romance options in the chat which was kinda offputting. Same with Cassandra who I saw as "my trustworthy second in command" and same thing but even worse with the auto-cutscene that comes when they agree with you enough. Or in DA:O/DA2(?) where suddenly the elf guy asks you for as threesome - what the hell? That feels like some horny teenagers wrote that in a blog, not professional writers.
PEOPLE saw the guy/girl walk out of the damn fade with a glowing figure of a woman standing behind him, he can close the things threatening the world right now of course everyone is going to like him/her.
As for why I brought it up, I didn't know what kind of orientation they were not at first, I got that information from the mutual attempts at dating each other or at least flirting. Flirting is a normal part of the human interaction, but just because its included in the game that you can flirt with a lot of people does not mean you have to.
Also as for your scenes that you got, you must have given them an idea you were interested in them, chosen a dialogue options that lead to it, I never got them, to me dorian was still just a friend, Cassandra was a trusted comrade. Solas, just a weird guy.
And in mass effect you did not have a "romance" button. You had to talk to them and you had to choose to say that you were interested. As for Allers, her entire inclusion into the game was a bit wasteful.
And anyway the whole point is moot, BioWare is not going to go back and give just one or two romance options, it has been their shtick to be as acceptable of sexuality of the player as they could get away with, I still remember the explosion of complaints from more conservative people(I am deliberately choosing a nice word to call them) about same-sex alien alternative in the first game. At least they didn't do it like in the DA2 where everyone seemed to swing every each way.
As for a non-crew romance option. Well one way of doing it convincingly if you start in the hub area, no crew, and you get to start a romance with someone there but then you get a ship and a crew and then you can either continue with it or leave it and start something else. It would be interesting to try but it would also require them to write a lot of dialogue and voice work for a character that might simply get abandoned a couple of hours in.
