For the Queen!

I completed the campaign on "Hero" difficulty. I can say that I enjoyed it, although there was a lot of running around due to the large number of castles in missions 1 and 3. The AI bought many heroes and ran around the entire map; in mission 3, for the Dungeon faction, even 2 Chaos Knights were running around with Shock and Meteor Shower spells. The skill build (for those interested) was through machines (machines, attack, leadership, logistics, and a fifth skill to diversify with Darkness).
