I believe that the deferred deployment is a great idea and saves some troubles. But, I have seen people take advantage of missed turns and have their total bonus be deferred if they miss a turn and would like to see this changed. If a person misses a turn they should only be allowed to deploy the base amount of men instead of the whole bonus held.
This tactic was used in a doubles game against me by both parties involved and could have easily cost us the game if we weren't good on the map.
