Kind of like in AC: Odyssey. Even then, people cried about it. Most were hostile because they had played their char as gay and having an heir wasn't on their agenda. They felt it betrayed the choices they had personally made during gameplay. Not to sound like an asshole, but, people need to get over it. Some stories make more sense if you have an heir.
With that said, I still haven't played in a few updates, so, am not up to date. As for watching this thread and reading spoilers, doesn't bother me.
