For me it's the appearance is a big part. And yes, my campaign is very Tolkienesque in regards to the general look and feel. It's also because of the ramifications that come with the appearance. But it's also an issue with the cultural aspects that I've noted before, and my dislike of using the Returned Abeir storyline. I don't care about the extra abilities at all, that's fine.
The elves, dwarves, orcs, and a great many other races are aliens to the Forgotten Realms. I don't have a problem with them being aliens. My problem is first, the story element that put them there, and second the ramifications of dropping an entire society of a culturally advanced race in the Realms. An event like that would have extremely significant ramifications, initially locally, and then expanding from there. Imagine that there's an alternate earth, populated by other intelligent races, and then drop an entire large country of us. We would have a huge impact on the world, and most likely not an entirely good one.
We have a historical precedent in the European settlement of North and South America. In my opinion, a culture as different, as regimented, and well established ex-slaves would not be a non-event. And I don't want the future of my campaign going in that direction.
The rarity doesn't bother me. I've had a player with a character using spellfire in my campaign. The issue is that if it's the only Dragonborn that's been seen, or maybe one or two more, then every trip to civilization becomes one centered around the lizard guy, and everything that entails. Sure, it can be an interesting story element. But either it constantly becomes a thing, or you ignore it, in which case being a 7' tall guy that resembles a dragon is kind of pointless.

I guess I can see where you're coming from, but a lot of this just confuses me.
First, why not just...not have your campaign go in "that" direction, whatever direction that is. Like, there's no real reason to assume Dragonborn are going to start invading people, or immediately get invaded (since everyone by the time everyone isn't reeling from the spellplague, Tymanther is up and running and ready to defend itself if needed), or interact with the world in any given specific way. That's up to you.
Second, so lot's of players playing a thing that's supposed to be rare doesn't bother you? Did I read your other post wildly wrong? I'm not being facitious, I just don't understand what your actual stance/issue is, now.
That being said, I don't think the idea, in 4e or 5e FR, is that Dragonborn are so rare that people haven't seen a few. I may be wrong in teh case of 5e, but that is still something you can determine for your campaign, either way.
If they are rare, that's fine, they can be a big deal, or not. If they aren't, that works too. Neither needs to turn every trip to civilation into a "look at the lizard guy", and whatever you've decided that "entails". I'm curius what that entails, for you? Because in my campaigns it entails...that race is reptilian, and that's about it. Like, it just isn't an issue outside of the same racist NPCs that fetishize gnomes and call halflings "rats".
I mean, they don't look like lizardmen, and no one is going to confuse them for one even if they've never seen either, because the dragonborn is wearing well clothes and speaking Chondathan. FR is full of weird stuff, some of which is bad, some good, most in between, and every single person in FR knows that fact. I can't imagine that seeing a race you haven't seen before, as a denizen of whatever Sword Coast farming town you can think of, is a source of shock, confusion, or even fear. Caution? Sure.
But a dragonborn in nice clothes, polished armor, speaking the same language as you, with a yarting on her back and eagerly greating people and asking where she can get some ale and a bath, is probably less cause for concern than a Uthgardt human in furs and face paint, glaring suspiciously at everything.
As for common Dragonborn, I don't think most people want to play DB purely for the novelty, so I'm not sure how not being stared at in varying levels of terror and confusion means that playing one becomes pointless. Like...playing a 7' tall dragonic humanoid is an appealing thing (or not) in itself, not because it's novel.
So, the idea that it "either it constantly becomes a thing, or you ignore it" seems like it might just be a you thing, not a dragonborn thing. Which I get, but that's the game.
I think halflings are a stupid race, and FR would be better if you replaced every halfling with a gnome, because gnomes do or can do everything halflings do, without being boring and redundant. But I know other people like them, so I deal, and recognize that it's mostly my hangup.
and don't get me started on all the elves and dwarves that honestly could just be elves and dwarves. Not to mention, why are there so many kingdoms of humans and each race gets like, one, at most? Seriously, I've heard or read all the excuses, but it's a forced thing, and it's always bugged me.
Now, all that being said, I'm not sure why they couldn't have come from one of the far off continents, with more details on those places, instead of the whole spellplague thing. I'm just saying, they don't need to be a big deal when they walk into town, any more than a human from a far off land, if that.
and I can't speak for your players, but mine have always wanted to play dragon people that weren't broken, didn't have level adjustments, could be played from level one, and weren't drizzt-y "this whole race is monsters, except you. and ted. everyone loves ted." it's not, for them, a matter of wanting to play it because it's in the book, but rather being glad that it's in the book, and balanced and official, so they
finally get to play it.
