I had a great discussion with my father. Some of his ideas were too detailed for even Total War, but it was great nonetheless.
I'd rather add something that would seem familiar to someone from Estonia than something that's historically correct. The problem is that peasant armies are useless in Dominions, and using huskarls feels like a cop-out.
To do:
shield guy; huskarl or pic+stat
Stealthy lasso guy (with entangling one-shot weapon); pic+stat
Removing the shield from stealthy crossbow guy; pic
Moose riders to
reindeer corps?; pic
Compact description of the flaming hooves of Hakkapelite cavalry; stat
Heroes (Väinämöinen, Kalevipoeg); stat
Heroes (Sage-smith Ilmarinen); pic+stat
Two heroes, all commanders, three summons, few other national spells and about half of the unit roster ready.
