I'm okay with what we know so far, and curious about what's next. My biggest interest is the whole Elune thing. I favour the Elune was a Titan over the Elune was a naaru belief. I think her being an outside, actual deity would be boring, and weird if that's the way Blizz chooses to persue the issue.
So on the whole my take on the NElfs is: Elune did it. Just unsure at the moment who and what Elune actually is to further the story.
