Once you get the hang of mouse turning its so smooth u will wonder how u ever clicked. If 7 or 8 are 2 far to get ur fingers 2 try using some keys closer, or key a game pad, my keyboard has a gamepad on the side with 42 buttons, only game i had everyone bound on was Age of Conan. If u have regular keyboard use Q,E,R,T,F,G,C,V,X,Z,SHIFT,CAPS,CTRL. You can also get a mouse with buttons.
Remeber best way for melee to keep on target when strafing around someone is to keep a finger on A or D at all times depending on which direction you are strafing in.
I'm sorry, what do you mean by "mouse turning?" Are you talking about using A and D to strafe and using the mouse to circle the enemy?
And, I'm curious, do you shift strategies back and forth between PVE and PVP or do you strafe and turn in PVE, too?
