Thanks for the review!
It would be good to write about the battles: which ones were difficult and which ones were not.
For me, during my first playthrough, Nela was incredibly difficult, and she killed a lot of my troops. During my third playthrough, I killed her almost without any problems, just in the field.
Regarding the -3 morale before the source, in my opinion, it was done intentionally because the author wanted to show that the enemy should and can be defeated with the available mana. Besides, the trip to get this doubled mana bonus takes only a couple of days, and those who are aiming for a speedrun playthrough won't go there anyway. So, I wouldn't deduct points from the map for this; I think it was done correctly.
Regarding Yogue's skills: earth + water + fire + wisdom. Intelligence is also essential, as well as accuracy. The other two skills are logistics + pathfinding (again, for faster playthroughs). Ballistics are not needed; I didn't need them anywhere in the game. In some difficult battles, you can simply take an extra ranged unit (e.g., cyclops), place them near the ballista to burn down the enemy ranged units and the ballista, or burn them with dragons or kill them with magic. So, in my opinion, ballistics are not needed at all.
You can add to the walkthrough that this map is truly one of the best, even though it was made a long time ago. After completing it, the player's experience in playing custom maps will undoubtedly increase. So, this map should definitely be added to the collection of completed maps for many reasons. I played the map three times: in 12, 9, and the last time, 6 months. Since most of the troops are given for quests (and not through accumulation), it is possible to speedrun and gather enough troops for the final battles by the end.
