Why is it that when WotC comes up with a new race its got to be splattered across all settings in precisely the same manner as they did in the original setting?
They did it with WarForged, they used their lame 4E version to ruin Tieflings in all settings and they do it with Dragonborn.
And Dragonborn are utterly the lamest attempt to do dragon-people I have ever seen-- from their mud-brown skin and their lack of tails and wings (taking away anything remotely "draconic" about them) for mechanical balancing reasons of all things! After all, in 4E they couldn't give Tieflings a balance bonus for having tails if Dragonborn had them too. Then there is the fact that they are 7' tall draconic creatures yet they are expected to be universally good and endeared to everyone-- even when dragons are the most recurring enemies, NEVER are they to be actually working for the dragons. And, of course, that this reptilian race has to show human sexual characteristics because if the girl ones don't have tiny waists and big bouncy boobs, then how is one to know which one is the girl? (As though it were somehow important for that to be immediately obvious and you couldn't just have it hard to tell with this particular race.)
It is just the worst.
Then again, Faerun already had something very similar-- they had the Dragonkin. So instead of forcing the utterly inept and gross abomination that dropped from the bowels of 4E, something I have a hard time believing even those who play them really wanted when they thought of Dragonpeople, why not drop the idea and just use Dragonkin or Draconians from Dragonlance?
As someone who stated playing during the 4e era and have yet to hear any reason why I should even take a look at anything older, I can tell you that playing a 7ft tall creature with scales and a draconic face very much appeals to me. And due to the good writing of Erin M Evans the two parts of Faerun I currently care about are Cormyr and Tymanther, with Tymanther being the part of Toril where I am truly interested in the culture etc. The rivalry or enmity with dragons (probably including good dragons) and avoiding the gods are very much part of why I like them.
The human sexual characteristics on dragonborn are bad choices on the part of artists, and I can see why non-asmodean tieflings are great as well.
