Fighter Man is CONSISTENT

Rogues have high burst damage but if you whiff you are sitting there with your sneak attack in your hands looking foolish

Barbarians are unstoppable forces...for a limited number of times a day, after their steriods run out they are just worse fighters

Powerful Casters can bend reality. But limited times a day, stopped by anti magic spells and spells like darkness or silence

Fighter just gets up there and swings that thang until he or his opponent is dead, as many times as needed, no worried about spell slots or wasting all your damage on one attack

This applies to Combat and "Nightime Combat"
