I was just thinking about zone denial. When you break an opponent's zone, do you generally leave the bulk of your troops in their zone's region or in your own?
I've noticed that when you make their former territory a choke point, it tends to provoke retaliation into your zone if they break through, however if you let them take the zone easily then they are content to regain the zone and focus more on bolstering their defenses.
Which is better, to break and retreat, or to break and hold it?
