Ok, back to the actual topic of this thread:
The major problem seems to be that players of Baldur's Gate 1/2 will expect 3rd Edition lore, while 5 Edition apparently changed a lot concerning Drow and Tieflings. In particular:
(1) Players of Baldur's Gate 1/2 will be confused that their Drow/Tiefling character is not feared, hated or receives at least surprised reactions. I have seen a lot of other people in this forum point that out.
(2) They will expect human-like Tieflings like Hear'Dalis and expect them to be special, maybe even connected to planar travel etc.
(3) They will be surprised that the sinister looking Tieflings like Zelvor express fear of the much smaller and more harmless looking Goblins
(4) They might be surprised by the exchange between the two Tieflings and Lae'zel, especially the remark about her looking so alien, because, to a human player, they obviously are at least as alien
(5) They will be confused by the Cambion which mostly looks like the Tieflings, but suddenly is evil and powerful
(6) They might be surprised by the rushed introduction of a benign Illithid in the Underdark
Possible solutions:
(1) somehow give players of Baldur's Gate 1/2 some narrative introduction that the world has changed and Tieflings and Drow are now abundant and not feared or hated much
(2) try to make the Cambion and the Tieflings look more different from each other
(3) try to somehow resolve the issue that the Tieflings look sinister but act fearful and innocent
(4) maybe move the Illithid in the Underdark to a separate hideout, which the hobgoblin reveals to you first by telling you about it and then later on by seeking him out. Maybe also add a few sinister/funny remarks of the Illithid, for example that he feels "your brain looks tasty" or something
