If you want to play a diude that stands there with a sword and board and faces down giants and dragons and stuff, it is right there. If you want to play a dude that flies intoa battle frenzy that lets him ignore pain and deal hurt, or has a hyper focus that allows him to stun enemies and leap chasms, those are there too. They just don't have the name "fighter." Play the mechanics you want to play to support your preferences, rather than complain that "fighter" in your head means something different than what is in the book. The image in your head is your responsibility, not the designers' or the GM's.
