I was looking at a old suggestion , and I was thinking why do orcs spawn in places in the lone lands where they are thousends of miles away from there home base? and for that matter why do orcs and urcs spawn in the far reaches of Rohan and Gondor? so I was thinking that some areas are ocupied by orcs, like the highlands, some areas are battle zones where boath good and evil troops spawn like rabbits, and zones occupied by the good troops. occupied zones would have structures, but warzones would not. thease zones whould be concreat, never changeing do to this being simpaler to add.
