I think the "community" asked for a couple of themes for the least years that we still havent seen, yet Blizzard picks something strange like Warlords of Draenor, that no one asked for.
Some examples:
- Emerald Dream: Pretty much requested since Vanilla
- Demon homeworld / Demon theme: People actually expected this as the upcoming theme and talked about this since BC.
- South Seas: People are talking about this since at least early Cataclysm.
It's not that I have anything against WoD, but the theme just strikes me as odd when there are so many other (better?) themes that people like and have been waiting for.
Especially if they want to get people back into WoW, wouldnt it make more sense to use the themes mentioned above?
