So, I was wondering if it was possible to add the entire Vashj'ir zone into a 3.3.5 server without updating the rest of the world to the post-Cataclysm state, as it's really the only zone I want from it, but have no clue how I'd go about it, considering the Classic world is smaller than the Cataclysm one (the end-of-zone boundaries would mean Vashj'ir would be out of bounds), it's very deep (going too low would result in instant-death) and, most importantly, is attached to the Cataclysm world.
