this formation is great! espicially with Macedonians. doesnt work well with greeks though cause of their greek cavalry. but what do i do if the enemy gets behind my line and my cavalry have been routed and i didnt recruit missiles so i dont have any troops to attack the enemy behind the line? should i "take off" phalanx formation off one of my free hoplites or/and pikemen and attack without the phalanx?
