Yea this really annoyed me, if you want nords and fans want nords just add the nords. But don't water down slav culture and the whole Sturgia faction just to have nords in, when you could just put them in!
I know they're trying to make Sturgia a mixture of both, but they said its mainly based off Kievan Rus. So shouldn't the factions banner at least look slavic? In the banner blog they just say "The Viking shield is perhaps one of the most iconic shields we can think of, so using that in the centre of the design was an idea we had right from the start (the sword just naturally fit in with that!). We combined this with a design taken from some Viking jewellery (a torc) which helped to bring the whole piece together."
So they add three nordic things into the slavic factions banner. Where the hell is the slavic influence?
