By the way, regarding Champions...
Just about 5 days ago, I finished a game with Lord on Spot. The situation was such that by the finale, I managed to gather 20 Champions and not a single Angel, as they weren't found among the neutrals or in the market. In short, I was once again convinced that Champions are by no means a weak unit. With a Tactician and a Life Mage, they are simply a killing machine due to their first strike (this is the main thing, as it reduces losses) and their ability to boost stats. Because of the Tactician, the initiative will be high, meaning the Champions will go first - there will be plenty of room for boosting (and in the worst case, you can run around the enemy in circles), and the Life Mage can heal or resurrect them if necessary. In general, I don't think Champions are too much weaker than Angels. I proved this to myself again in a recent game :)
