I'm hoping we get better maps of Randland as the series become popular. IMO none of the maps are very good. The best I've seen is one for sale on Amazon. It's a map of Randland is the National Park map style. It has a blown up view of Tar Valon, but there's not a lot of detail. Link
This is the most simple and legible one I have found.
This may not be what you are looking for but I love this national park style WOT map on Amazon. I bought it and really think it’s fantastic
