It would be more advantageous to take a hero of a different faction. That is, as I suggested in "Faction-Specific Abilities," use similar gameplay schemes.

Although it seems to me that the system will be more similar to the magic system in Heroes 3.
That is, spells appear randomly. And the same spell will be in different schools.
