It's just weird to hear all this about LGBT rep when its just B with an admittedly bad rep of T in the last game.
Now though, we're seeing LGBT rep in full. Well, if Maevaris shows up, or someone else who's transgender. Glad she was done right, according to transgender individuals who commented on her. I have yet to hear/read anything negative about her that wasn't obvious hate for the sake of it.
The representation also applies to the player character.
If you have 4 romanceable characters, yes they are all bisexual, but the player character can be bisexual, straight, or gay. And no matter which one they choose, they will still have choice.
In terms of other forms of representation we can still use non-romanceable characters for that representation too.
