lol the problem is the enemy has more than 5 cav....
if someone play 3 or 4 battles on M2TW with normal rules will understand that 90% of the armys has around 10 cav so this tactic only works if the enemy is a noob..If the enemy doesn't take cav probably the enemy took factions like England or scotland, Scotland with theyr pikes won't give chance to aztec infatary and Scotland can take many cav too , maybe only agains England this tactic will work but even England can take many cav..
