I think it would be cool if you had a 2handed weapon that could be sheathed at your side just like a 1h weapon, but when taken out it is held and attacks like a regular 2h weapon. Also, a cool addition would be if when you run with a 2h weapon you hold it with one hand instead of running weirdly holding it with two hands, but still attacking while holding it with two hands. If somebody could make either or even both of these mods I would really appreciate it.
