We had that with a certain male druid elf, who basically was just a romance without story.
When you eventually arrive in Baldur's Gate together, he's maybe a bit like Sandy Cheeks, out of his element but still part of the gang. Most druids would even suffer debuffs, if staying in urban areas for too long. In the first two acts he is quite heavily involved in the story, though.
I'm looking forward to Larian's take on scaly folk. If I remember correctly, Dragonborn were introduced into D&D during 4e, with no context given and a description saying they just happen to resemble the dragons to whom they are not related, however. Typical WotC-slop. The continent/scenario they came from only existed in 4th edition and was apparently completely retconned away for 5e. There were several draconic races in 2e and earlier, even ones available as player races, but they weren't native to Faerûn. So, while I did enjoy some of the dragonborn NPCs on the humorous side, I'm quite glad they weren't overdone in BG3. Now I hope the BMG brings back puzzles!
