Actually Gambrinus, that's a perfect idea. It allows a good dose of strategy by allowing people to control armies, as well as making it balanced by having a cool down for the rally. the Devs could make it so that by the iron age, players are able to build a new building that allows the creation of specific formations that the player can define (ie. 10 infantry, 5 archers, and 2 cav) and designate it to a flag, on the battlefield when the flag is dropped the troops come out in that formation specified and go on their raiding ways, and to rally them do what you say and place the flag somewhere else.
