dual wielding was mostly impractical, unless you trained in it for a good portion of time, however, there is no benefit of doing it in the current game, because two weapon fighting was about fluidly swinging your two weapons around and hitting from multiple directions, or unexpected angles, or making multiple fast attacks in a flurry of blows, which is not possible in life is feudal. the only type of dual wielding that could be implemented would be similar to Skyrim dual wielding, which lets face it, was completely ineffective, and had almost no uses.
