I'm not sure if it has been asked or not but, why did the Horde settle their capital city in a desert with next to nothing useful and barely any farm-able land. Or if there was no other choice but to settle there why didn't they try to at least change the land into a more liveable place?
Couldn't the Hordes shamans call for help from the elements or the druids heal the land and restore it to have lush forests or grass lands? For me it seems like they had no reason not to do it or it seems silly that they wouldn't be able to as the Horde has many capable shamans and druids like Hamuul or Thrall for example.
