Hey Sparker, thanks for the thumbs up!
Of course its pretty rare that dual wielding is left out in any medieval-fantasy game/movie/anything as it always looks cool and shows a lot of dynamic. On top of that its an easy way to create a third option besides sword+shield or twohanded weapon.
Despite this we decided to not implement dual wielding. The main reason for this is that I personally dont think it makes any sense at all in pseudo-realistic medieval fighting (maybe apart from things like a main gauche).
Discussing this topic can be very tricky as people tend to have a very strong opinion on the subject hehe :)
