Monks, Legacy Type Controls and Auto Attack

[Ehayte]

I don't really understand what's being talked about here. I use Legacy controls, am I losing out on Damage or something when I strafe around enemies?

No - if you STRAFE you are fine, if you actually turn your whole body to run (as you would on a controller by moving the joystick without locking on) then yes you are missing damage. And yes it is significant.
