The issue I am trying to explain, is someone had to have less options due to wanting to add romances. It is true that Vivienne could be an option, and I agree with you that she would make a good one. The complaints have very little to do with the dissapointment. I get why guys were dissapointed. Many of us can empathize with the disappointment and have said so on many occasions. We also don't think you guys deserve to have less (and neither did Allan).
The point is that straight guys so often have extra that when extra time came along, they decided why not give it to someone else? There will be times when someone has extra, nearly all their games have an extra romance for someone. And due to a certain logic, it always went to straight men.
It isn't your disappointment that we call entitled, we can empathize and understand and agree with the disappointment. It is only when you act like it is a punishment and that you somehow are being attacked by not having the extra that you come off as childish. The idea that you are sending is if there is extra, it should be yours, and if someone has extra and you don't, you are somehow being punished and are wronged. That is entitlement.
Imagine This: Straight women get more options for the next 20 years. Eventually Bioware listens to guys and says, woah thats not fair, next time we have extra romances to hand out it will go out to someone else. The next game comes out and lo and behold straight men have more. And the Straight Women are acting like they are hated, that they are being targeted, and raising a big stink that someone has more than them and the options aren't that generally appealing. Straight Guys natuarally point out that the gals have had more for awhile, and its only fair that they sometimes get more. And the women act like that is an attack too because the men want revenge and are out to get them. They would be childish and entitled.
Or even think of this, if the next game has more options for straight men, will you think how unfair, Bioware is punishing straight women, or think hey! Awesome! Now I get more options, that seems fair after DA:I. Many, many people think no one should get extra and that is awesome. But next time someone brings up balancing romances, remember it has as much to do with Straight men being unable to deal with having less than someone else; as LGBT and Women wanting the same amount.
