I've noticed that a lot of people that should probably react negatively to a drow, don't really care, and that a lot of drow dialogue options are missing. Obviously missing/mixed up dialogue options are a bug or something, but hopefully people reacting to my drow as if they're an actual drow will be fleshed out down the line. Nothing more immersion breaking than coming across a group of people who just got attacked by some drow raiders, and then my drow character comes strolling up to them as they cry over their dead friends and we just have a normal conversation. You would think they would have a much more negative response to seeing a drow right after a bunch of drow killed their friends, but nope.
