Character Pitch Rotation Problem

So, I am in the third person template, working on an online First Person Shooter, so my problem is, when I enabled pitch rotation, which is very crucial, instead of my character looking down or up on rotation, he instead magically floats his entire body downwards and upwards, I believe i need a looking down animation, or I need to fix something, because it definitely does not look right. What can I do to correct this problem?
