Haven tactics.

I recently played a game and tried playing as Vittorio. I used a combination of Ballista, Knights of Isabel, and Catapult when sieging the city of Bali. In the very first turn, the gates were destroyed, and then a group of knights charged in, and the enemy didn't have any defenses. I played on a large map and didn't upgrade the troop tent yet, as there will be plenty of time for that. That's it. Plus, I had luck, leadership, and attack bonuses. I didn't upgrade light magic, but it would have made it even easier. I completely rebuilt the city in 4 weeks, and nothing bad happened. I played against Necropolis. The most dangerous units were the Harbingers and a thousand archers, but they were gone after a couple of turns. They were fragile. Anyway, I won.
