Legion only fan service?

First off, I'm pretty happy about the expansion. Of all the things it could have been, this is pretty damn good. I'm REALLY happy that Sargeras is getting close, and that this is basically a Night Elf expansion. I couldn't ask for more (apart from Old Gods) in that respect.
However, is there anything new at all in this expansion? Everything mentioned so far is just a call back to TBC and Wrath with Vrykul/Dala and Violet Hold. In a way I am excited, but there's nothing...new.

I didn't find the right solution from the Internet.
