They could give us a city elf origin. It wouldn't cost them anything, it changes literally nothing since we won't even met our dalish clan. But now, op is right - playing pro-dalish makes no sense story-wise and playing as a dalish it makes no sense for them to be anything but pro-dalish.
It clearly does since every character we come across comments on our vallaslin, our Dalishness, and the stories/stereotypes of Dalish they have heard.
Besides, considering the entire second half of the game deals with Elvhen history, lore, ruins, religion, issues within the Dales (which the Dalish better remember than city elves; whose understanding of their own history has been eroded away to near non-existence after hundreds of years of humans breathing down their necks) and meeting our long-lost Mother Goddess, I felt it was really fitting to be a Dalish.
I don't think trumping up and down the Exalted Plains, the Emerald Graves, Emprise du Lion, the Winter Palace in Halamshiral, the Arbor Wilds, the Temple of Mythal, meeting Abelas, encountering the Well of Sorrows, meeting Mythal, or using a stolen ancient elven artifact to defeat an ancient magister would have quite the emotional impact or personal relevance if we played a city elf. And I love city elves, don't get me wrong; if asked whether I would rather play as a Dalish or a city elf, I lean toward the latter.
But the Dalish have such good story reasons here.
BW decided for us what our character will be. And this is bs. I hate how all our responses to Solas are offensive at best, you can't even roleplay playing as an elf, you're pro-dalish and you know better, period.
Yours, maybe. Almost none of mine were.
Besides, have you actually played past Haven? It's true your first conversation with Solas about elven culture has to have a "We Dalish are awesome" response, but after that Lavellan can calm down and can take many pro-Dalish stances without being belligerent or hot-headed about it, and we can approach other elven characters as a fellow elf instead of a self-important Dalish imparting sagely wisdom on poor city elves.
When Solas asks if the Anchor has changed your morals or spirit, and then asks if he was mistaken about the Dalish since they raised someone with a spirit like yours, you can respond "yes." And it's not in a jerky way either. Lavellan, male and female, romanced or not, just smiles gently and says, "I don't hold the Dalish up as perfect, but we have something worth honoring. A memory of the ancient ways."
Whenever Sera rips into the Dalish and/or elves, the Dalish Inquisitor can be calm and patient while defending his/her culture, and merely diplomatically point out the good things we've seen / ask her couldn't there possibly be something worthwhile there?
When Josephine asks what was life like among the Dalish, you get several responses ranging from "I loved life among my clan," "My clan sucks, I couldn't wait to get away," or "Our lives were terrible because of humans. Boo, humans!"
What I like about the game is that NPC's tend to foist the "offensively xenophobic Dalish" stereotype onto the PC, and we can decide for ourselves if we want to live up to or disprove our stereotype. Just about every conversation with a companion or NPC about the Dalish yields at least three separate responses with at least one erring to the side of politeness. Even the conversations with with only one "Special" Dalish response tend to be more diplomatic.
