Are we playing the same game? Both of my Drow have had Drow specific dialog. Maybe your version is earlier than mine, and my choices were added later? One of the lines was akin to "If you see red eyes, run", when talking to one of the Tiefling children in the Grove.
Again, however, I don't want Larian writing a backstory for my custom characters, and I'm still really amazed at how many people here seem to not only want it, but need it?
Did you even read what I wrote or just skimmed through it looking for keywords?
Ugh, I did write that the race and class do come up in dialogues. But unless you missed it, you can choose your background:
This is my main source of complaint as it never comes up in dialogue.
So it's there but unused. Totally pointless.
