The instance cluster takes place in a re-imagined version of the city and does not replace the original, existing instance. It's a new piece of landscape/dungeons built with modern world design in mind.
Ahh, okay. Sorry, Scenario, but that sounds just a tiny bit too inconsistent to me... I don't like the idea of the world becoming... *disjointed*, like "re-imagined" here or there as in a brand new take, but the old one still existing in the other place. I like things being consistent if they can be. Which they could have been here. At least that's just an instance but still... the idea that you guys waste time redesigning old stuff that worked (honestly, what was wrong with the old Carn Dum visually? It felt great and everyone says it) it just doesn't sit right with me..
