1. "Passage garrisons" have been weakened. Now there are 3*10 snipers, i.e., a total of 30.

+1

2. The map is difficult (the strength of the neutrals is very high), so I introduced events for the players' starting Castles, which give new recruits on day 7 and every 7 days thereafter. Recruits: level 1 - 20, level 2 - 10, level 3 - 5, level 4 - 1.

In my opinion, this is unnecessary, as it will make development too easy. It would be better to give a certain amount of resources through an event, or even better, simply enrich the map with resources (let them be guarded, but they will be there).

3. The guard of neutral Castles has been increased by 2 times.

I don't even know about this one, as I need to try playing it first.

4. To further enhance the advantage for quickly capturing neutral Castles, a replenishment of recruits in the Castle has also been introduced, according to the following scheme: level 1 - 40, level 2 - 20, level 3 - 10, level 4 - 5, level 5 - 3, level 6 - 1.

In my opinion, this is also unnecessary, although again, it is necessary to "test" the map.

P.S. I still haven't found the bug with Wisdom. I specifically checked the skills of all heroes, and everything is fine; where is the problem hidden... hmm.

In the editor, next to each Castle, there is an undefined hero of the corresponding color. Therefore, at the start, this hero will be the one you choose at the beginning of the game. So, in the properties of the red hero, on the "secondary skills" tab, there is the "Wisdom Expert" skill. ;)
Yes, and one more thing: will the Tournament use exactly your latest version of the map, or will the previous one remain?
