"So, we could choose not to release the fixes, and then it would be just as obscure as a random map, but slightly/significantly improved by a professional..."
I absolutely agree, BUT the balance needs to be adjusted so that all Castles are equal on any map. Not so that on certain maps, one Castle will inevitably defeat another, meaning that the landscape and a sufficient number of the most necessary resources at the start should be taken into account first. Otherwise, it might turn out that there will be only swamps, and it will be very difficult to play with other Castles against the swamp. Or a situation where you are on your territory, where there are few resources, and you can only get to another area by killing strong guards. And you don't have wood to build stables (you only have a sawmill, and you need to wait 2 weeks to build it, while your opponent has already broken through to the center on day 121 and is already thriving there) or, even worse, some resource to build Eyes in the Dungeon.
For example, I played a couple of times on that duel map "Me and My Shadow" with a Castle. There seem to be enough resources, BUT it is problematic to break through 55 snipers at the start, because even improved horses have a speed of 9, and they won't reach the snipers in one turn. And one volley from 55 snipers, and you almost have no troops left. It's generally difficult for Necropolis. One option is tactics, but what if you don't get tactics? Moreover, on that map, it's not worth buying more than three heroes in your own territory, because you will still have to wait a couple of weeks to break through those snipers, because the chance of leveling up tactics is very small. But with a Swamp or Rampart, the snipers are easily broken through on the second week. Therefore, I would add either a witch hut with tactics or a dwelling of some fast creatures to block the snipers to that map. Therefore, the balance of a particular map can only be achieved through repeated testing and testing each map with each Castle. But in principle, this map is not bad (I liked it, but it is very large in terms of both size and the number of quests). There are maps in the seasonal tournament that are much more unbalanced. I perceive them as a way of saying "life shouldn't be too easy."
