its the best way really. strafing side to side isnt enough, its predictable. circle strafing generally makes the opponent stop moving, especially inexperienced ones, so they just become fish in a barrel.
ah ...so you mean actually circling around the opponent?
it all depends on how near you are i suppose,you cant circle somone if your aways from them. i prefer side to side jumping at long range, and in close combat i run away and hide.....
