Not at all, jerry.

Changing from semi to fully automatic is useful for a variety of situations. Let's say you have an Assault rifle, such as the Ivana (TAR-21) from goldeneye. Need to silently headshot a guy from a distance? Semiauto, aim, shoot. Need to gun down a bunch of bad guys charging at you? Switch to full auto and spray like mad.
