For me Battle Brothers is very realistic tactical medieval combat simulator, so that’s why dual wielding should be added only after proper research.
I’m not a member of The Association for Renaissance Martial Arts but I have some knowledge about medieval and renaissance fight and I can assure you that in real fight dual wielding was only use with light weapon like dagger, knife, hatchet, etc. Dual wielding was used generally for better defence. In Battle Brothers it should gives you better defence, and bonus to riposte. So forget about extra attack ;)
