Having read what has already been written, and given the author's desire to make some adjustments to the map, I would like to share two somewhat different thoughts. Ideally, they should not be mixed up randomly. So, the first thought: the map in its current version – without the "AV" spell, with mixed garrisons, etc. – is a quite successful piece of work. It has become a map for simulating game situations, on which it is convenient to practice different hero upgrade options and Castle building tactics. Development proceeds quickly, and you can get an assessment of the result within a game month. There are guidelines from Rambo1969 for this, and you can also see how far the AI, which also developed in isolation, has progressed. In this context, the existing garrisons are a good idea. They allow you to use a variety of schools of magic and spells. There is no point in strengthening them or setting up a guard consisting only of Titans and Dragons – this raises the bar for the player's skill, but most people would benefit from simply learning how to use magic correctly. Perhaps, it is worth only bringing the main garrisons to a single type. Currently, they differ in the set of creature upgrades. The outer dwellings can be completely removed, or you can leave levels 1-3, but near the Castle. Their presence is a useful asset for non-magic races. For the Tower and Necropolis, they play a secondary role on this map (for the Necropolis, I built a Castle from two dwellings and a five-story magic tower – this is quite enough to win).
The second thought. The map space is still poorly utilized. More than half of the surface does not participate in the events. The changes made have not solved this problem. You can compare screenshots from Rambo1969 before and after the editing – the amount of explored area on the map has hardly changed (the same is true for me). The vast area behind the two-way teleport is dead. The proposed changes are not capable of reviving it. It is necessary to completely change the road system, add new roads, which in turn will significantly change the entire map design. So, there is a question to consider: is it worth doing finishing work when the foundation has "shifted"?

how many points do you need to get to get the "Black Dragon"? :confused:

In version 3.1, the "Thunderer" is the highest-level unit.
