By single-handed I mean using only one one-handed weapon. I don't like the current system how it shoehorns you into either using shield and sword or dual-wielding. I, and a few others I have talked to, would love a skillset for using a single weapon in combat. At the moment there is no reason to use only one one-handed weapon, in fact its a detriment.
Please be the one game where they don't force you into using something in your offhand, there are many very appealing fighting styles using only one weapon in one hand.
