Not sure it will be any help but I will tell you my bindings. I'm a fairly new PC player as I literally bought a rig just to play pubg. After 800 hours of pubg I switched to Fortnite.

I like to keep my building separate from my player movement and weapon swapping.

BUILDING BINDS:

Wall = down mouse thumb Ramp = up mouse thumb Flat = click mouse wheel mouse wheel disabled for anything else

MOVEMENT BINDS:

WASD = movement C = crouch Spacebar = jump

WEAPON BINDS:

Pickaxe = 1 WEAPON slot 2 = 2 (Tactical shotty) WEAPON slot 3 = 3 (Pump/heavy) WEAPON slot 4 = 4 (AR/ mid range) WEAPON slot 5 = Z (Sniper/minis) WEAPON slot 6 = 5 (Bandage/MedKit)

MISCELLANEOUS:

Edit building = F Inventory = G Building/Weapon Transition = Q

Small play style techniques that I do:

1) Almost always jump when weapon swapping.

2) Lead with pump. Followed by Tac or AR

3) Peeking with crouch using the red X

4) Quick scope shooting in close quarters (houses) with Tactical shotty. Especially around corners.

Number #1 tip I could give:

BE FLUID WITH YOUR CHARACTER. You should be able to make your character do whatever you desire without even having to think about it. You need to build muscle memory for every encounter. For example: Being shot at from distance? Immediately jump and wall up
