And I'm over here on the opposite side, because Bull and Sera are two of my favorite characters in the entire franchise. 
And Bull is my boyfriend's favorite DAI character and Sera is my best friend's favorite DAI romance. I understand. 
It's a tough balance. I think what Bioware's ultimately going for is subverting expectations... we heard about Briala in TME and we knew we were getting these elven companions in DAI, a magey elf and a city elf, and I think people were expecting boy-Merrill and blonde-Shianni. Whether it's a good idea narratively speaking is up to individual interpretation, but it just makes me want to steeple my fingers and mutter iiiinteresting under my breath.
Though it's worth noting that all these super understanding, non-racist human love interests are still the minority in Thedas. Interracial relationships are still very taboo. I mean, even Fenris and Merrill stress over how their being elven will affect your relationship, and Gamlen has icky things to say about it. And you can discuss your elvishness with all the LIs in Origins (especially that one conversation with Leliana...).
I guess that's just another problem with BioWare's "show verses tell" policy.
While they like to subvert expectations, they also need various characters/companions to "represent" the groups they're from. For example, in DAO Alistair represents Ferelden culture and Templar worldviews (at least suspicion of mages), Leliana represents Orlais and Chantry religious views, Sten represents the Qunari, Dog represents the Mabari (a cultural treasure in Ferelden), etc. In DA2 Anders represents Andrastian Circle mages, Merrill represents Dalish (mage) culture, Isabela represents Rivain, Fenris represents non-magic Tevinter slaves, Varric to surface dwarf culture, etc.
The trend continued in DAI, but I think they take it for granted that people have played or are aware of previous games, because while some characters still "represent" their home group (like Dorian to Tevinter), BioWare also makes them the exception of that home group. Again, Dorian to Tevinter, Bull to the Qunari, Sera to city elves, etc.
In the case of elves, I think this creates a narrative imbalance since we're told one thing of elves but we're constantly shown another. We don't encounter scores of important elven characters everywhere the way we encounter scores of significant human characters (Alistair being the "exception" to the Templars is fine because we run into plenty of zealous Templars; Leliana having unorthodox views for a devout Chantry sister is fine because we encounter plenty of orthodox Chantry sisters and mothers) so it can be hard to swallow what we're told about elves compared to what we're told about other humans.
Being told, "Elves are abused," "Most humans are prejudiced against elves," and "Elves typically stick together," but, apart from one or two side characters in side quests that are easy to miss, constantly being shown elves living well, being treated well, humans being kind to elves, and elven companions being dismissive and judgmental of their people can make it seem like elven characters' claims about their circumstances are lies. I mean, Sera gives credence to all elf haters who say, "Elves just stand around barefoot whining about oppression when they're just too lazy to make something of themselves. See? Sera's an elf and she said so!"
Again, "show verses tell" impacts how a story is received.
Heh, it all depends on your character's goals! Merrill will discuss what it means to have children with male Hawke, but I think that's the closest we've gotten to that kind of conversation... adoption is always on option as there are (sadly) probably a crapton of elven orphans around, or you could end up with elf-blooded human children. It's something to bite your nails over, certainly. I love it when culture and romance conflict - in fiction, anyway.

Yeah, Merrill mentions it once in a quick throwaway line, then it's never brought up again.
Feynriel is a pretty good example of how human/elf children feel, being brought up knowing they're part human and part elf but don't fully belong in either. Then again, his particular circumstances were that his Dalish mother abandoned her clan to marry his human merchant father, who abandoned her soon after, so he longs to be accepted by his father and his mother's people alike. (Then again, he's a mage revealed Dreamwalker, so it makes sense he would want his mother's people rather than the Andrastian humans he can "pass" as--they would let him be free instead of locking him up in the Gallows.) I think TME reveals that Michel de Chevin is the opposite--his mom was also an elf who raised him alone, but he prefers his human heritage and tries to "pass" as fully human, and is openly racist against elves and is ashamed of his elven heritage.
Anyway, I don't have it in me to create such an elven character who is 100% okay with discarding her elven culture and discontinuing her elven heritage. Even if one of my elven gals loves her human hubby so much she can barely stand it and she loves her human children so much her heart bursts just holding them, part of her will always wish her children could be elven, and then she'll feel guilty for feeling that way, then try not to show it because she doesn't want to upset her human hubby or child, and then the guilt will just eat her alive. Or, she would feel she has to compensate by thinking of the child, "not as a human, but an elf in human skin," but that's not healthy either. Not to mention it might cause problems trying to treat her child like an elf (singing elven lullabies, telling elven stories, teaching them elven traditions, etc) since the human father would think, "Yeah, I know our child is part elf and it's both of your heritage and that's important... but s/he's my child too. S/he is human too. We can't neglect his/her human heritage." And then part of her will worry that if her child gets too big a taste of how awesome it is being human, s/he'll reject being elven. (Turning out like Michel de Chevin would be my elven gals' worst nightmare for her kids.) And then there's the fact that the elven community will never fully accept a half-elf human child--it's just a mess. There's always worries and considerations.
Even adoption is not 100% stress-free, since you get into the pros and cons of birth-children verses adopted children, and will both partners be okay with adopted elven children like the elven mom but no human kids for the human dad? Then what if birth control fails and they end up raising their birth kids beside their adopted kids? Then you you get into considerations of birth children raised beside adopted children, some kids being elves like the mom but some kids being human like the dad, and it's just a lot to think about.
OH MY GOD I LOVE THIS. I have always loved Merida and Young MacGuffin, so this is hilarious to me.
It's brilliant, because I based my CE Warden on Merida. She wasn't a fan of that arranged marriage business.
LOL glad to be of service!
I like using characters and fictional couples I like as base models for my own characters and romances. For example, I loosely modeled the mage Lavellan who romanced Cullen after Aisling from The Secret of Kells, and her romance with Cullen loosely (very loosely) resembles Aisling's friendship with Brendan. (A white, pagan "forest fairy" who breathes magic and befriends with a kind church boy.)
Yeah I think instead of spending extra time burning the midnight oil to make sure Bull could romance dwarves, I think extra time should've been spent doing the same thing for Cullen. And finish the male recordings for Solas and adjust the slight height difference lol I would've only gotten one that way, but hey it's better than none. And everyone else in this thread would've gotten Cullen. But, sad Bull-loving dwarf fans... dang, guess everyone can't be happy 
Nevertheless I still scratch my head at Iron Bull being the only non-race-gated, non-gender-gated man in the entire game. (whispers) That should have been Cullen.
WHO WAS NOT EVEN INITIALLY A ROMANCE OPTION LIKE WHAT.
Yeah... I don't know what they were thinking.
I guess Iron Bull was the lead animation director's favorite character (forget his name), so I guess I can understand why he would pull out all the stops, but really... HOW, in three years of production, did so many people come together day after day, week after week and say, "Yeah, the ladies (and gentlemen) will totally want Iron Bull/Blackwall more than they'll ever want Cullen." Really? How did so many people over three years get together and say, "That's a good idea"?
