Vertical warfare, promotion of camping, and bad map design choices

I wonder too how the map design could have went so sideway between the concept and the final product. Was it for performances, to make it more childish friendly nice shiny unscratched, because some head-of taste were different ? 

Hourglass concept too felt much more interesting. More scattered buildings, more objects, better repartition, more atmospheric dust etc ... 

PS : i wouldn't mind skyscraper buildings if there were more opens. Different floors available, different stairs to access each of them. Can enter from the windows etc ...
