Cavalry. cav in this game PULL AGGRO EVEN IF THEY DON'T GO IN FIRST. Go in with 4-6 to draw fire or clear a path. Use a single cav to "save" infantry being gunned down by towers. He'll pull all tower aggro. Send cav in on one side to distract catapult, then send in infantry on other side. Cav are the absolute KEY to minimizing losses. You WILL lose a lot of troops if you don't use tanks, there's just no way around it. I'm medieval now and my typical army (farming) is 6 cav, 25 melee infantry, 15 archers (chu ko nu), 1 miner. On many raids i lose only the miner and a few infantry. Infantry are the units that go down most easily, simply because theyre ahead of the archers, despite their higher hp. Try to take out outlying ballista towers with 5-7 infantry EARLY. Hopefully theyre on the outside of the settlement. Once ballista towers are down, cav are practically invincible.
