The things OP criticized were obvious ever since they put out that weird in-engine trailer with Bolvar's narration and all of the zones looked like they could just as well be places on Azeroth or Outland. The whole "we're going to a different plane of existence" schtick automatically turns into an exercise in futility if that plane of existence behaves and looks like the normal world for all intents and purposes. In terms of aesthetics it's also basically just the "Can i copy your homework? - Sure, just change it up a little so that it doesnt look you copied it" meme.
