It seems it's not possible to change the "Set waypoint" key bind (Left Shift + Left Mouse Click).
It's not a problem for, I assume, 99.9% of the users, but since I use the Left Shift to change the stance (Crouch/Stand up), if I go prone in a bush or something, then go to the map and set a way point, I go to the crouch stance.
Not a good thing if you want to remain "cloaked" by the bushes... :)
Got me killed multiple times, in BattleRoyal, for example.
Anyway, it's not a bug or anything, but I personally would like to have the option to change that key bind.
Thanks!
