I think the paths (warrior, defender, assassin, mage and governor) should replace the professions (scholar, adventurer, hunter, general, warlord, ...), because the paths ...
- should be unique
- should define the hero
- are more powerful
- should improve the army in addition to the other effects:
- Warrior: + 5 attack to all units if only one hero is in the army
- Defender: + 5 defense to all units if only one hero is in the army
- Assassin: + 2 initiative to all units if only one hero is in the army
- Mage: + 10 spell resistance to all units if only one hero is in the army
- Governor: + 2 movement to all units if only one hero is in the army
