I really wonder if the Designer for The Black Shroud has ever entered an actual forest. Its designed almost like a city... In a forest you're going to have hills, fallen trees, old huge trees, saplings, glades, rodent holes in the ground...

Just one giant tree, or one aged, fallen tree (or maybe a tree that appears to have fallen before its prime), all adds wonder and and interesting things to the zone with relatively little effort and resources. Why would a young tree fall? What might have made its home in an old fallen tree that is now rotting?

How about the giant redwood-like trees from Zi'Tah that you could walk UNDER? What about trees that make a home exclusively on bodies of water?

Honestly... just a little research =\
