Living a life in a dilapidated ghetto doesn't sound like something the city elves should have to endure anymore. The city elves endure persecution and purges, while the Dalish isolate themselves from Andrastian humans who threaten them; the developers and the lore note how human lords and lynch mobs drive them off the land if they stay too long in a particular area, while the Chantry outlawed the elven religion in the Andrastian kingdoms. I think the Dalish and the city elves deserve better than the status quo they've had to endure for close to a thousand years now.
I don't disagree with the principle (people deserve certain rights and equalities), but I am coming to disagree with the idea that the City Elves and the Dalish have a singular common problem. I think it is two very different problems with two very different answers.
Setting aside for a moment the fact that the Dalish are hardly a unified body, maybe the answer to the Dalish problems is a Dalish homeland. Call it a republic, and have it allow them to stop wandering, and build a nation suited to their beliefs. But make no mistake, it would need to be a
Dalish nation. Not an Elven one. Because what the Dalish hold dear and valuable and worthy are different than what City Elves would consider to fit those descriptions.
In some ways, when the Dalish say they are the last of the elves, they are right. Culturally, they are the only purely Elven society left. Regardless of how well it does or doesn't match Elven cultures of old, it is still a purely Elven culture. City Elves, by contrast, tend to view themselves as National citizens first, and elves last. And while they might hold on to the odd tradition here and there, culturally they are whatever the nation they live in is. Ferelden city elves are culturally Ferelden. Kirkwall city elves have Kirkwall's culture. So a joint homeland may not be the best solution for them. Most, obviously not all, would likely say they already have a homeland. And trying to force that union on them would be no different than trying to force it on any other group of disparate citizens. What they need are improvements to their standing within their own nations.
And trying to combine the two groups increasingly sound like disaster to me.
