I'm not one of those people and comes on this forum to complain, or voice my opinion that often, so bear with me. The look and feel of the Legendary weapons, have just as big of a role in the portrayal of these Legendary Lords, as their models and voice-acting.
This is a great example that the "little" details make a BIG difference. Instead of a Zweihander sized sword, which he wields with one hand (because he's so powerful), he has this slender short-sword. Considering he's supposed to be this imposing and powerful Vampire Lord in melee combat, why portray him this way?
I hope in a hot-fix, or even next content patch, they can make his weapon the proper size.
