Maybe its on purpose. Maybe as a prequel Lenneth hasn't quite gotten very "battle-hardened"
Mind you that brings into question what she's doing in Valhalla in the first place, but hey I'm trying.
valkyries dont need to become battle hardend they just are. lenneth was a badass in VP1 until her emotions/memories got in the way.
anyway my money is on this being a reboot wich is a complete fucking cop out. i dont really care for her new design either.
