Locking Zones of Control: Do you use them?

[ComradeP]

There is not always much of a practical difference between locking zone of control and no locking zone of control with ZOC multiplier 0. You only benefit from it if you can move a unit into a position so that another can retreat. If you don't have (many) reserves, your units still can't pull back.

I guess there might for some scenarios be a substantial difference in movement between locking ZOC and a multiplier higher than 0, but if it's 0 you'll still need a second line full of units that can move forwards in order to prevent encirclement.
