Up until the previous edition, being turned into a drider was seen as a punishment from Lolth to all drow who didn't receive her favour. Well in 4th edition all of that changed, it was then seen has being in Lolth's favour so it was considered a blessing.
Do you think they will go back to the original lore or will they retain the new?
Chalk me up as another "I hope not" vote. It makes more sense for becoming a drider to be a reward--driders are literally closer to their goddess, even in shape.
