I don’t know about you, but to me the place in the concept doesn’t look enough like Rata Sum to think it should be used for it. The Rata Sum concept art used looks like another city out in the Desert somewhere, the tree’s are different, the temperature is different and it has an almost chaotic layout for buildings, as if they’ve be slotted together as time goes on.- Rather than Rata Sums very balanced pre-determined placement. It feels like a different place. This does happen quite a bit with the concept art used in loading screens but this one was more extreme than others.
I dunno, I’m just being picky probably. But I really want to go to the place we see in that concept art!
Anet, if you read this, please consider another Asura city that looks like this in future content way down the track. Maybe in Maguuma Wastes, or Elona.
