I would only like to see a couple more things in DayZ and I will be the happiest zombie in the world, Day/Night Cycle (If there is already then does it go by your timezone?),the delay of dropping things, zombies not being able to walk through walls, being able to go upstairs AND downstairs without seeing the "Open Door" sign for the door under you, vehicles, better jumping, take less fall damage from falling 4 feet from the ground, less controls, and lastly being able to rush up stairs/ladders.
