I hope that they go back to driders being considered a curse.
I always saw the drider transformation as a punishment because it was reflective of the punishment Lolth went through herself. She wasn't always a spider-with-an-elven-head deity; she used to be a beautiful elven goddess before she lost her war against the Seldarine, and she was cursed by Corellon Larethian to be a demon and to have that shape.
Her transformation of "failed" drow into driders is her re-enacting the punishment she suffered, where she now gets to be the tormentor instead of the tormented. I always saw that as being very apropos of her nature.
See this? This is the kind of thing I in no way want to see anywhere near a core product. To me Llolth is a demon and always will be. She became a god through her drow cult.
Everything you just said should never appear in a core book. I mean I don't even know what a Seldarine is.
Ultimately, what's the difference whether they list Lolth as a demon or exiled (and transformed) member of the Seldarine in a core product? If you want to use Lolth in a campaign without the Seldarine, you can.
I always thought the transformation to a drider would be considered repugnant. The drow are after all elves, viewing themselves as beautiful to behold, and to become a bloated spider, hideous to family and loved ones, would be quite a curse. I thought this original lore interesting and did not strain my imagination. It made the drow more 'human' in their sensibilities, though they worship a demon spider, the thought of becoming one is abhorent. Ultimately, there is nothing to say that both lores couldn't be true; that in one drow community, their worship of Lolth is so intense that many aspiring drow volunteer or even compete to become driders. Where in other communities, where no one volunteers, Lolth forces this on the least capable. In both cases, Lolth and her clerics require a certain level of driders, one way or another.
