Difficulty

Instead of separating difficulties levels I would like to see all maps include all difficulties. Areas of the map present different difficulties ie...suburbs with plague walls (I hope all maps in the future) and plague hearts would be nightmare difficulty. The idea and reasoning is the more populated the area the more zombies. Furthermore the closer you get to plague walls/hearts the more infected zombies to include plague ferals and jugs. The outskirts of the maps would be easier due to less zombie encounters and less plague exposure with basic ferals and jugs. This way all community members are playing the same game but some would enter parts that are more challenging/rewarding
