The Above is an exaple of a Main Gate. Notice 3 footman are blocking the entrance to the city, and cleric and Conjurer are far away from enemy's projectiles.
I usually put the catpults behind Archers (close range setting) because orcs seem to concentrate on destroying the catapults rather than the Archers. Catapult Projectiles will miss for a single Target, but if the enemy approaches your city in a fleet, Catapults will do a great job. You must understand that gates can be easily destroyed if an enemy catapult attacks. Stay alert and if you see a catapult, send a Knight to destroy it before it can reach your City. Do Not send Archers.
Knights can be used as bait, as well as Catapult killers.
Since orcs don't organize their army units, you can send you knight to their visual range, and guide them to your gate. Keep doing this until a city becomes empty (except for Peons, and in some cases, Necrolytes). If there are any catapults in the city, don't send you men. Send water elementals. If your city is well guarded, waiting for you conjurers mana to fill up should be an easy task. If you can make the water elemental invisible, that's great. Remember, making Elementals is cost free, but training your units costs money. In most cases, scorpians are useless.
