Ravenloft has good ideas in it. Dark Sun has good ideas in it. I don't want either to touch the core D&D experience with a 10 foot pole. I want them to be their own unique flavor of D&D. I don't want Eberron's unique takes on things to become core any more than I want Dark Sun's take on magic or Dragonlance's take on gnomes of Ravenloft's take on fear mechanics. YMMV.I really disagree with this. Eberron is not great because it's different. Eberron is great because it has good ideas in it. D&D has been getting closer and closer to Eberron over the years (alignment, less racial definitions and more cultural definitions...) and I think it's great!
Even as someone who thing D&D is best served buffet style with lots of options to mix and match, I don't want Eberron's unique ideas to get whittled down to warforged and magi-tech.
