The removal of the zone rule makes the "park your robot on the sides of the field and cycle balls really fast" strategy feasible. The inbounder robot parks in the corner and shoots it to the human player, who immediately puts it into the second robot (against the side of field in third zone), which rolls it into the third robot, which rolls/shoots it into a goal. Rinse and repeat. All robots would be in a corner, so you can't push them out of the way.
