This has been a weird coffee diary.
For the record I think the Exanima weapon proportions are all pretty good. If we're going to get anal and compare the Exanima swords to museum pieces and testimonials by weapon experts, it's good to keep in mind that museum pieces are all surviving pieces. There could be many other different variations of swords that are proportioned slightly but did not survive the passage of time.
Also if we assume that the swords are slightly off proportioned keep in mind this is a 3rd person game with an aerial view, if a sword component is slightly too big, it might be for visibility purposes.
So basically I would agree that criticizing the weapons of the game for being slightly too big or too small in some places is kind of pointless especially when Madoc has said they are still being worked on. That's assuming the swords are even incorrectly proportioned, I really don't think they are.
