I really enjoy MoP, and so do most of my friends. And even as an asian themed expansio, there's a lot of variety. The zones all have very different landscapes (except Dread Wastes which is Townlong but with sha corruption everywhere). We see various forms of architecture. Don't like the flashy stuff in jade forest/vale? That's fine, how about the villages in Krasarang and Valley? The mantid archtecture? The bits of zandalari we've seen? Hozen and Jinyu? I don't think it's a problem at all, and heck, in 5.3 and 5.4 we won't even be on Pandaria for the main content.
