The most important aspect of running is to control your center of mass and posture. Mistakes made in running posture and or your center of mass cannot be corrected by changes elsewhere in your running form. Any changes made in an attempt to correct mistakes made from center of mass will simply lead to a compensated error that will usually end up creating a new set of problems, but at the very least it will make running more complicated than it needs to be.
An example of this is very often a runner's hands will be too far in front of them, this shifts their center of mass back. The runner now throws his or her feet out in front of them and this results in an inefficient heel strike with increased impact. Changing how the foot lands on the ground now becomes a compensation that requires thought and or effort and is less efficient and may lead to injury.
