The world doesn't even make sense. I mean Thanalan's desert suddenly transforms into a forest at the Shroud zone line? Where's the transition? I always felt there was a region missing between those and even on the world map it looks like there should be a desert area that turns into a grassy area followed by a river and then grassy before going to forest. Shroud itself makes no sense. If you've ever been north of Nine Ivies you'll see the area is miles above the ground, yet on the world map it's all flat.

I don't think they can fix these areas. They just need to be forgotten about as soon as an expansion comes along and adds new areas. Then again we aren't even using Coerthas and Mor Dhona for content yet or the 20 or so dungeons that are locked away.
