Also would like to point out that I do understand how important terrain is in this game.

Each biome is unique, this isn't just for appearance but plays a huge role in tactics.

Doing the concept first to understand the enemies you want to develop then doing the terrain to match that is key in how they do their world crafting. An important step you need to do in order to populate the area properly with the enemies you want to introduce.

So it isn't as though I deny the importance of the work being done... or think it is a waste of time or think they could do it faster or anything.
