Its very unlikely that one would be able to switch out a sword for a bow if he has to put it on his back while an enemy chasing or coming at him
I say we should be able to have quick drop button or when in combat switching out a weapon should cause you to drop it for faster weapon switching
i would also like to point out that keeping a bow strung fpr more than an hour or two would be horribly damaging for the bow (it would get warped and lost all its power)
finally is there a weapon oiling system since there is a resharpening feature will we have the option to oil our swords and bowstrings to keep them good condition whille in storage
