Oh yes, funnily enough I was planning to ask this as well. Playing as Macedonia, my phalanxes seldom seem to get into any straight on fights, especially if they're defending. Even the AI isn't dumb enough to charge into a forest of pikes, so everyone just flows round the sides and attacks them from the flanks. As a result, my cavalry has to deal with the enemy army while my pikes try to turn around. Am I doing something wrong?
