instead of just giving the units a number, it would control an annoying bug.
OK, just say you have a Sumo and 10 freakers (attack version) and you asign them the "simple formation" AI. in a normal game if you told them to move, the Freakers would arive there before the sumo; so i propose that the AI would make all units go the speed of the slowest unit of the group. Anyone get what im saying?
