@jimnms why can't half-drow be followers of Lolth? I mean, sure, they were born from Seldarine drow....but that doesn't mean, one cannot worship the spider queen.
I'm sure they can in the tabletop rules and lore, but the game doesn't let you be Lolth-sworn if you are a half-elf drow. Sure, I could have still picked it and role-played that I was a follower of Lolth, but they mentioned in a live-stream that they drow were made a separate race instead of a sub-race of elves for gameplay reasons. So I'm thinking there might be something I would miss out on in the game by not taking the full Lolth-sworn drow.
