Might I add that I absolutely love what you've done with the Spider Noble feat.
Thanks! Alex and I spent a couple afternoons going through the Species feats with a fine-toothed comb, folding in comments and answers to your questions and looking for imbalances, but also to try to really dig in and figure out how to improve them across the board. Glad you're liking the result.
I'm actually less happy with it... I like old school driders who are outcasts of their kind,
This is still covered by Spider Nation.
and Drow Noble is an actual creature in AD&D and Pathfinder. So now there's really nowhere to go for non-spidery nobles.
Not sure if I'm understanding your comment here, but wouldn't non-spidery nobles be better covered by other feats anyway?
