So player A has an HPA and everyone knows it has random movement. Player B has a fast calvery unit that can free reform. So what if the Fast cav move up to it exactly 1 inch away exactly parallel to it. This would technically make the HPA unable to turn at all and be forced to move straight forward the whole game correct? Reason being is when the HPA moves it could never pivot on the spot without getting within 1 inch of the fast cav unit, thus making it go only direclty forward. Looks like this would work to me as long as the fast cav were able to keep up and it didnt get killed by magic or shooting. What do you think?
