I installed the patch. On the more difficult versions of maps, where you can't choose a hero (I don't know what it's called), the AI's growth rate increases by 8 times on Heroic difficulty and 4 times on Normal difficulty. I barely managed to complete the Deathlord maps on Heroic difficulty, The Fall of the Lich was a bit easier, and I couldn't complete Angel. I had to set the AI to Normal difficulty for the first three. Personally, I liked the patch; it made me remember the fifth Heroes game, and I had to sit in my castle and defend against an enemy with an army ten times larger. Destroying catapults, and so on. The only thing I didn't understand was the AI's income level; it shows Normal, but they have enough gold for a huge army. Once, I received 250,000 gold as a reward.
