Defence strategy

Answer from: Cleo3322
I'd say a mixture of all troops so you have a range of different defence and attack techniques! Also try to upgrade your lancers, Sentrys and Berserkers to level 2. As it gives you a good advantage!! You can never have to many troops ;)

If 5 or more waves incoming, it's probably a clearing wave, followed by 4 - 5 scholar waves. Move all your troops away someplace to dodge the first wave (let your wall do/take all the damage) then recall troops that were outgoing so that they're back in camp before the 2nd wave hits. You want to let them lose their expensive scholars. they need time and resources to make more, thus avoiding them capping your city. There could also be a few fake (1 unit) waves thrown at you in between, just to confuse as to which ones probably have scholars.

I've been using the battle simulator alot to work out what seems to work best. Lancers seem to be an average unit that dosn't do too well in attack and defense compare to Sentrys who seem to do better in defense and Berserkers seem to do better in attack.

I have 3000 guardians in every city (level 3). They seem to do the job. Guardians have the highest amount of points in everything attack or defense.
