can a long full circle arm action cause problems?
i see a lot of people with shorter arm actions, and throwing hard.

Depends on the pitcher and their body. If the timing of your body requires more of a long arc, then you need that time to get loaded. If your body works quicker, then the shorter arc is needed. As long as your arm is loaded properly, the distance it takes to get there is relative to the time you have to accomplish your task.
