They should also add sheaths for weapons. So weird seeing my dual short-swords hanging on my back like they do. If I fell over backwards, I'd double stab myself

There is this guy on Youtube who tried to make a proper sheaths to carry his sword on his back. There are some advantages to this (which would require a special custom made scabbard/sheath) but even him admits that there are some risks when carrying weapons that way (it's not as safe indeed, and not necessary historically accurate) :
hereThe video as a whole is interesting, I recommend ^^
And those dual hand crossbows should be placed on the hips rather than lower back. Next patch for sure!
Yes! Omg, please! Let me feel like Lara Croft in D&D 😄
They also look incredible odd hanging on the back anyway x)
