Detailed Training Mode / Rolling
I think there should be a training mode which will help explain and display reaches for all the varying weapons so you at least know or get a feel for how far you can attack. Possibly putting a circle around your character for whichever weapon is equipped. And highlighted sweet spots for maximum damage.
Also and maybe could consider adding a roll and rolling attack. Would of course take stamina maybe as much as a kick or so to add a little more pizzazz to some fights and make you more unreadable.
