Plus, all of the other heroic Tevinter characters have been male, so it'll be nice to get a woman to start balancing things out a bit.
(yes, Cal is a woman. I said 'heroic'. Also, being a companion means she'll be more integral to the plot than Cal, who can only be met on the Templar route).
OH I forgot about that, good point! I'd say it's time we had a female qunari as well, for the same reason.
Given how how awful their track record with BioHair (I'm definitely stealing that term)...
I can't take full credit. I was inspired by a recent spree of developer tweets where they were using BioWare in a similar fashion, "munching on a BioPear," and so forth.

This video (thanks to Dalinne, who posted this in the MEA section!) explains, in a response to the criticism of a trans minor NPC in the BG expansion, why both flat and round characters are necessary. That also applies to representation. LGBT NPCs are nice, but they're mostly flat characters. We need LGBT companion (which are always round characters) to get a full representation.
I agree about flat versus round, and that companions are round and thus offer truer representation. However, I'd say we need a healthy mix of both to make their inclusion in the world seem "real," otherwise people can just point to all of our followers, most of whom have been available as romance options, and say that they are catering to the player's fantasies in that, as in everything else, and this core group of people isn't truly representative of Thedas at large. So I think it is important to have NPC pairings like Celene and Briala, Wade and Herren, Leliana and Marjorlaine, Sera and Dagna (I LOVE these two together).
Yes, not being too hurtful to who they are, you can insult them and kill them, but what does it have anything to do with them being a transgender? You judge a person by their actions, not their characteristics. I probably wouldn't have focused on the transgender issue at all, and just let transgender be just another character. Bioware was wrong for the right reasons, but you're wrong for the wrong reasons. You are obsessed over a minor character, talking about how transgender characters are untouchable despite how you could kill them. You have problem with their existence, and I doubt Bioware cares.
This subject is a bit moot anyway, since Bioware has shown that they don't have an interest in allowing the PC to be overly bigoted about anything, either sexuality OR race. Elf PC's can't go around calling people "shem," humans and other non-elves can't go around calling elves "knife ear," no one can remark on skin color, and no one can refer to particular sexualities as "disgusting."
Bioware has been completely equitable in the disallowing of bigotry for the PC, and that is completely fine with me. For all my thoughts and opinions about roleplay and having the most variety of options possible (within reason!), I don't care one whit if that makes me a hypocrite; I am glad that that is Bioware's stance.
According to Gaider, whenever they bring a character from the EU to the games they give it the same treatment than to a new character... And for me it does feel that way...in some cases, seems even out of character compared to the one displayed on the comic/book in fact.
The biggest example we have so far is Cole, since he went from book to a full follower. For him, I think that any changes we noticed in DAI are explained by the events of the book, and by Cole himself. I didn't find the changes off-putting at all, and indeed thought they made perfect sense.
I don't really want to participate in this particular discussion, but... emm, there are actually some straight men who like being pegged by women and they have 0 attraction towards men. I'm N.O.T. saying everyone likes it, but those who do are neither bi nor gay.
I tried to explain that already; didn't work. It's just a hole with nerve endings, and men have a happy button inside. I don't see what the big deal is.
