Defending Defending

Wall defenses are very important, but you want to have the right stuff. first are traps, they're only used once and then they're gone. the same is true for abatis. U want to have both tho to be able to help with infantry and calary. Next is archer's towers, the best of all defenses, they have life instead of a one hit rule. Rolling logs are helpful against large waves of infantry but only build a few because u want room for towers. Defensive Trebuchets are good for getting rid of those pesky Ballistae but don't overdo it. i'd say aobut 100-250 tops.

Next if u see a large attack of archers or warriors but no pike then build calvary and swordsmen and open ur gates. this will help minimize losses of archers towers and traps.
And finally have ur Beacon tower at lvl 8 or higher so u can tell who's attacking u and wat they have and how long they'll take to get to u so u know wat u can build.
