5e decided that good drow instead of being rebels or heretics who have made the decision for themselves, there is now a city of GOOD drow who live on the surface who are good so drow subrace one evil and one good. Because the whole fun of playing a good drow being the tragic, romantic exile who broke with tradition for justify wasn't fun enough for them?
In game it seems to mean, has background raised in Menzoberranzan AND still worships Lolth, v raised outside of it and never did.
Playing a drow from Menzoberranzan who rejected lolth appears not to be an option? as a cleric it's your only choice. Viconia from BG1 cannot exist under BG3 character creation rules. Drizzt also not possible.
Also the new system of it being subrace not individual choice that determines alignment and religion is uh. a step backwards. I hate it.
