You can do this basically without facetarget..you just press V to see behind you, and Bio or any attack as you're running away so you can target people who are chasing you...
Is that really a cheat?

Anyways, thanks for letting us know about this. If this fools people like you, it's good for some use in PVP.

And yes, you have to be using legacy controls to be able to run backwards quickly and easily. They are way better for PVPers anyways. Why everyone is not using Legacy Controls is beyond me.
