Secondary skills in Heroes 3.

Scouting, Eagle Eye, Tutorial - absolutely useless skills!!!

"Tutorial" is a completely useless skill in experience-based tournaments!
"Scouting" is a completely useless skill online!
"Eagle Eye" is a completely useless skill on maps where there is no magic tower in the starting town (if you want, I can tell you where to find such a map)!
You convinced me. :D

And skills like Navigation, Mysticism, Pathfinding, Diplomacy also become useless in some tournaments!!!

This statement can be said about absolutely any skill! because in different situations, completely different skills are required.

Sincerely.
