For lack of originality, Blizz is using themes based on real life concepts that exist because frankly, you can only make up so much in a fantasy world before stuff starts repeating itself. Not tired of the Asian theme but rather lack of innovation or that something new that makes WoW addicting as when it first was released as Vanilla. The only new stuff I see from expansion to expansion are lore related, tied into the quests, dungeons, and raids. Same car but a new coat of paint.
