My personal favorites are Yrsa, Astrid, Nox and to a lesser degree Matilda's ass and Astrja.
That's why i really don't like the new restrictions for girls depending on the clan you play...i liked that i could choose Yrsa and Astrid in every clan before.
So now my main run is the Raven's cause i get both, Yrsa and Astrid (but beside Nox, the Raven's have no other good girls imo).
BB - Dislike Candrid and Katja, no interest in Sonja, which leaves me with Yrsa, Matilda and the slave girl. Turned from my favorite clan to the least favorite...
WW - is ok, but no interest in either Sonja or Lizgard.
Raven - Nox, Yrsa and Astrid yay, but again Lizgard and Katja...
It would be lacking as a viking game if we could not give the Blood Eagle to someone, my personal choice for it would be Candrid and Katja.
