As far as I'm aware, it's the only, or one of the few, exclusive areas that allows you to return the your last position on your previous map. This allows you to go to the mistlock, unload your bags, refresh salvage and harvesting tools, etc, and return to your previous map and continue. It also has excellent crafting station layout, and quick access to fractals. Compared to LA in particular, it has faster access to trading Post and guild bank
