They have all my support (and I'm very sad to see the amount of negative comments they've gotten) but I have to say I do find Shadowheart as a pick to be strange. Her story doesn't highlight any sort of LGBT narrative or identity at all. She just has one vaguely flirtatious line about Karlach. Almost reminds me of when Viconia flirted with Hexxat, but she's straight. I think SH's very easily considered playersexual. At best you could read certain lines her dad has as a metaphor for deadnames and parents disowning children over their transness, I suppose.
Dame Aylin is a better more coherent nomination for sure since her romance with Isobel is important to her narrative. I guess they could've included Nocturne but she's a very minor character and in my opinion, when it comes to her trans identity, super clunkily written. Two of Astarion's most touching scenes acknowledge that he's been with men in a way you can't ignore (When he was in the tomb for a year because of letting a guy escape and the Sebastian scene), too, so I'm surprised not to see him there.
I think maybe Karlach could be a candidate as well, Samantha Beart mentions how she played all the romance scenes with a female Tav in mind, and Karlach's act 3 romance scene seems to be a
scene if I recall correctly? But honestly I think her character also falls into a lot of traps playersexual characters do.
Halsin is undoubtedly into everyone, as he specifies as much, so not playersexual. But I also wouldn't say he's exactly noteworthy for that or anything so I don't think he'd be a good nomination.
