My number one priority w/the Expansion. The game will be still difficult when playing a faction like Frisia. Historically Frisia was depopulated by the 5t century and had become a shadow of itself of several centuries ago but you will have at your disposal, units and an economy that can potentially hold its own plus, the Franks need to invade the heart land of Frisia by the sea.(or cross a large river by boat) Watching the game play out, it doesn't happen. Any case you will have a good faction standing w/Sahson-Saxons to your East and the Thurngia will be at first will be in a major struggle w/the Alemanni-actually epic to watch he AI play it out...
