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?
Uh just to slide in here before this turns into some massive back and forth. I believe Nicottia wants dialog that's like [SAILOR] or [CROOK] based on character background. This of course might not implemented yet or not at all. I'd honestly prefer to choose a God than get [URCHIN] specific dialogs.
