We discussed this in the Turkish forum today. Calling the current Campaign map "not beautiful" is not fair imo.
Yes, perhaps you want dark-themed map. However, details and amount of work put into the current campaign map isn't something you can ignore just like that.
Here are some screenshots that I took today to disprove that claim.
You can even see a lot of details when you zoom in to models
Also, let's compare it with 2015's map
or
I think it's obvious that which one has more details in it and which one looks more realistic.
Furthermore, this one is from the same year.
You can see that the entire map is almost flat without any height difference apart from random mountains. Current map has more elevated areas which create more immersive campaign map by showing the cultures how they should be like. ( Battanians on high ground, Khuzaits on steppe etc) The current map also has not just texture but also vegetation type difference as well - different types of trees on different regions etc.
Also, I'm leaving this map image with ridiculously simple icons for those claim that old icons were better and more detailed
As you can see from images, it's also really dependent when are you looking at your map ( i.e, summer night time is different than winter evening )
