Some weapons sheathe on your back, others at the hip. As a Monk, I think most 1 handed weapons, if not all, sheathe on your back. Would be nice to be able to toggle whether you'd want them on your back or on your hip, ala Dual Sheath Redux, a mod for Skyrim. Would also be cool to have several weapons on your person at once, especially as a Warrior with the Weaponmaster glyph that lets you swap between weapons whenever you shout; Having two or three swords or maces and a dagger strapped to your back and on your person ala Geralt of Rivia would make a lot of sense and look pretty cool, imo. Again, another Skyrim mod inspired this, Armored to the Teeth.
I remember seeing a post about cosmetic add-on items, like a quiver for Hunters, maybe some poisons for Rogues, tomes and librams for Paladins, that would change as you level up. A Warrior may benefit from some sort of battle harness that would allow the cosmetic equipping of extra weaponry; An axe for Shattering and Heroic Throw, maybe a specific sword for Bladestorm etc.
Just something I was thinking about. What do you guys think?
