I think we have every reason to include melee weapons of at least SOME variety, since no combat force in existence would ever be caught dead without them. Sooner or later, you WILL run into situations where you are either in too-tight close quarters to shoot effectively, unable to fire your weapon for some reason, or just out of ammo. You'll also run into enemies where cutting them half or squishing them is just more efficient than riddling them with bullets. In those situations you WILL be glad you're equipped with a combat blade, hammer, or spear or some sort.
Just because the word "shooter" is in the genre description, that's no reason to pigeonhole ourselves into a situation no sane combatant would ever desire.
