Harmony - Troop Symmetry

Well, it's simple:
Humans hit 3 times stronger with oversight (leadership + defense + light)
Demons are summoned instantly (logistics + darkness + ?luck/attack?)
Necromancers shout 4 times stronger (summoning + leadership + education)
Warlock hits with elements 30% stronger (luck + chaos + wizardry)
Elves always hit with luck (light + luck + logistics)
Wizards learn all spells at the expert level (machinery + education + wizardry)
Dwarves hit with bad luck with a normal attack and just a lucky attack (summoning + defense + ? Leadership?)
Orcs gain 500 points of rage (leadership + machinery + attack)
It's easiest to get specializations for the Warlock and the Elf, because these skills are fundamental for them.
I probably made a mistake somewhere.
You should have seen the specializations for Talanar in "Higher Vampire" and "Defense"

And what is the new specialization for the Elves?
