Thanks! Looks like I need a little (well, more than a little) practice.
But when you're doing a group PVE mission, they don't mind you running around in circles?
You get used to it surprisingly quick. I recommend a left-hand key pad, takes getting used to but becomes very intuitive, though that is my personal preference over the keyboard.
As far as a difference in PvE, I am not sure what you mean by running in circles. If you want to stand still just don't run.
