Thank you for the map; it's good overall, but it clearly needs more difficulty. At the "hero" level, the main battles are completed without losses or with losses of only 1-3 percent of the troops (which shouldn't be the case for the maximum difficulty level). Also, increase the protection of creature dwellings, increase the aggression of Loran, and either remove the ability to purchase artifacts or increase their cost to at least 300,000 (otherwise, it's just another easy win, close to cheating). Finally, don't give the fully built-up elven castle at the start (otherwise, there's no need to save gold, and buying troops becomes not very burdensome, which also shouldn't be the case for the "hero" level).
