Haggish vs. Orah.

Thank you for your response. I have another question regarding hero development in this situation: did I develop the hero correctly, or did I do something wrong? To reiterate, it's difficult to predict which skills will be beneficial (Dark Magic is almost always a good choice), and I didn't choose the Castle faction due to logistical reasons – this map is very inconvenient without good logistics. Also, how should one generally approach playing a Mage on large and very large maps, considering that time is a factor and it benefits him, as he can gather more powerful artifacts for his units and collect the maximum number of useful spells (if we're talking about large but resource-poor maps, where even spells are scarce). Building a game strategy based on finding artifacts is also not very smart, as you can't always find what you need. We always play on "Hero" difficulty, and the development speed often depends on the units defending mines and important resources. I would appreciate help from experienced players, as I'm planning a rematch and don't want to repeat old mistakes.
