[ANNOUNCEMENT] Heroes 3: World Tournament - an add-on for tournament games.

For Eagle Eye, there is a very good enhancement - visiting upgrade buildings and mills from a distance, like in HotA, fits wonderfully into this skill.

I think that's very far-fetched. I would develop the original meaning of this skill, as was done in WT, only simpler and stronger - for example, at Expert Eagle Eye, in a battle with an opponent, you can fully view their spell book and learn N number of spells (regardless of whether a spell was cast). Moreover, you could start using them right away in that same battle.

In my opinion, the game should have junk skills

Why? If all skills were roughly equal outside the context of a specific situation, the game would become much more interesting.

Although there was a proposal to reassign the Speed class to it.

When playing with classes, Navigation is taken very often, even at the first level-ups, because it is already part of the very useful Explorer class (Scouting + Navigation = +600mp at Expert)

And where is all this? Looking at the above?

WT, of course, wasn't perfected, but they chose the right direction (excluding HotA nonsense like experience and tax). Specifically regarding secondary skills - the variety of progression there is much greater than in SoD, you don't have enough 8 slots for all the useful skills. Whereas in SoD, besides Offense, Defense, Logistics, Tactics, Earth Magic, and a few other secondary skills, nothing else is needed.
