For me, it completes the lore that I felt missing, making the timeline closer to reality. The “new” undead added celt and romanized legion, the vanilla houses are those feudal sires, the orcs and goblins are just basic fantasy setting, but what about the norsen pagans? They add them in this dlc. I kinda enjoy the middle age Warhammer setting, so, maybe just for me, these barbarians are fun to fight against.
