Hello everyone!
I have a problem with the last castle. The fastest rush doesn't work, and sitting and accumulating resources isn't an option either, because the AI also accumulates. As a result, see the screenshot:

This is how long it took to accumulate resources. Moreover, I have 3 castles and a lot of barracks, while he has 1 castle with a barracks. The main thing is that he has elite creatures, and even my numerous basic units can't defeat them with numbers. Maybe I'm missing something, but I can't come up with anything.
