There's really nothing you can say, sadly.
I know it won't be in this game, if that's what you mean by asking for the impossible. So the only thing I can do is try to get their attention by showing my disapproval of the current situation. As for taking a shot, I just get angry when people who have representation complain that they don't have enough when there are people who don't have any at all.
It wouldn't be fair of me to impose on you what I would do if I'm disatisfied with certain decisions creators make in things I could potentially enjoy (and thankfully, I've been pretty good at picking my fare). Yeah, it's true I'd get upset because why wouldn't you? I seek to find characters that speak to me in ways heterosexual characters can't, but for me, if I had always relied on outside sources for representation, I'd go nuts- primarily because I just grew up imagining and writing stories I'd wish to see for myself.
But that's just me and you're not me. I don't want to be that guy, but, you've tried writing your own stories and your own characters, haven't you? There's got to be a market out there for sexually ambiguous protagonists. In fact, the literary parts of the Internet I run around in are screaming for it. Sure, it's not Dragon Age and it's not something that you can just sit and enjoy, but that's one way of dealing with the lack of what you want there.
Someone's gotta do it, though.
For what it's worth, if I were on the writing team (ha ****** ha), I would have loved to have written this kind of character because I imagine it presents certain emotional turmoils and interactions you probably can't find with other orientations.
Why does representation have to come in the form of a romance?
Sometimes, I wish it didn't. But most everyone is a sucker for a good love story.
