The fact is, the game doesn't make anyone's sexuality clear, and there are a number of characters you can assume are LGBT+, from secondary characters like Jandelaine and Gaia to major characters like Aymeric, Ryne, and Graha.
But that's never enough, it seems that the importance of knowing the sexuality of character X and Y is greater than anything else. Like "wow, blizzard assumed that Soldier 76 is LGBT+"...ok, so what? Did anything change in the game? He keeps acting like he's just a war old man, as far as I've played, he never mentioned it in the game.
I'll leave my comment here, just to say that I warned: you will end up making the company create super stereotyped characters, who say every 5 minutes that they are LGBT+, and then you will complain that you are being disrespected.
And before you distort what I'm saying (because I know it's going to happen), I don't care if the character is LGBT or not. I care about the story, whether it's interesting or not. Because of that, I think a natural character is much better than super stereotypical characters.
