Nah the default keys are kinda dumb.
w=forward
a=strafe left
s=back
d=strafe right
q=lean left
e=lean right
f=use
r=reload
caps lock=run/walk toggle
c or ctrl=duck
space=jump
g=drop weapon (you can sometimes trick the other team if you have one of their weps)
x=holster weapon (this lets you run faster

I use this setup and it is absolutely perfect You should try it. Your current setup is what's getting your ass kicked
