Pivot needed in FPS?

When making a fps is the pivot needed for the player, of will a camera work fine. Will I have any drawbacks down the road?

By using a pivot and parenting the camera to it, you can rotate the camera without rotating the pivot(player). In other words, the player can 'turn his head'.

Check out my FPS code example in my sig.

yes, especially useful to look up and down without to alter the walking speed. Usually I turn the player pivot left and right, and turn the camera up and down.
