That's probably the whole point of Pandaria. It *isn't* the World of Warcraft that we're used to and that is the stage for a return to Alliance vs Horde.Now we have Asian theme that permeates thoroughly MOP and Pandaria. It is overwhelming, very dominant. It is not sufficiently diluted with other stuff as it used to be in previous expansions.
From a design standpoint, it was a huge risk. It could have triggered a worse mess than WotLK in terms of getting it released in China, and another mess like that would have caused subscriptions to bleed like an artery had been slashed. It could have flopped with Asian gamers -- those Asian themes you're talking about put them going head to head with popular, local games. It also opened up the various less than congenial relations between different parts of Asia as something that might cause a player backlash. That's just on the Asian side, and there are ample threads here to show the various reactions to MoP outside of Asia.
MoP put the conflict and characters into a different setting that allows Blizz to address things in relative isolation from existing lore, with at least some explanation for why they've done so. That's probably a good thing. As an artificial solution, I find it easier to swallow than the now obligatory ritual of "and once again you won't be able to fly until level cap" where they've stopped even trying to offer any justification other than game design. Over the course of MoP, we can expect to see them move along on Varian, Garrosh, and even Wrathion, the graphics are just window dressing.
