Everyone should make their own decision, however, I favor the mercenary option. TinCow's excellent counterargument aside, there is a question I asked myself. Why use an artificial and convoluted system when there is a clear and in-game option for us to use?
I especially like TinCow's point G. What happens if the remaining player has fewer units when the war ends then he recruited during the war? Can you have a negative number of units?
