The point of people coming around and being like "I hate diversity for the sake of diversity" is so perplexing to me.
We're humans. We're varied and strange.
Why the sod shouldn't the characters within a fictional medium be representative of that?
Is it so wrong for folks to ask for representation in games? Be it from the point of view of race and ethnicity, political views or sexuallity? The norm within most mediums in the west for characters is white and straight, which isn't really great because that's not the default for humanity itself.
And you can make the argument that it adds nothing to the character, but that's not true. Every facet of someone's personality is critical in discerning how they interact with the world and other characters. If sexuallity is something relevant to that person's existence, then it informs how they live their life. Tracer being a lesbian is critical to her as a character because she has a girlfriend that she interacts with regularly and is intimate with. If the statement "Tracer is a lesbian" was fact without any narrative context to back it up, then yes it would serve no purpose, but hers DOES.
And as I statred before, Riot has at the very least implied the sexuallity of champions before. Illaoi, Gangplank, Azir, Camille, Varus, Kassadin, Lucian, Ezreal and Lux come to mind. All implied to be straight but never outright stated. If Riot can do it with folks who're implied to be straight, then why not with folks who could be gay, bi, pan, a, trans or whatever?
Diversity is the default for humanity and by asking for less of it feels like you're actively asking for the things people make to be more boring for a lack of varied characters.
I seriously don't get this argument. Sure having it someone's sexuallity shoved in there with no narrative context is perplexing in and of itself, but when it's done properlly, has narrative context and works, then what's the issue?
The hell's wrong with diversity?
