is it possible, to make a new key map, for putting away the weapon? More times than none, you accidently Put away weapon in the heat of battle, cuz, its so easy to accidently push down LS when doing combos involving that LS..

You can map buttons on Xbox if that's the console you are playing on. I personally map the sticks to hotkeys so I can use them for quickslotted skills. But I'm sure you could also make it so this doesn't happen. Good luck ?

Left stick in isn't put away, It's Auto run: which puts away your weapon also. I am not sure but if you make sure you have no auto pathing set, it may avoid this issue.

For reference draw/put away weapon is right stick in.  Which can be done on the fly while moving/sprinting as well, without stopping ....a very handy little trick to know.

Although I agree, all keys should be mappable/lockable in the settings menu.
