That said, those character sheets (and designer comments about roles, etc) are what I've got to work with, so I'll try anyway. In 1st, 2nd, and 3rd edition, the fighter was the guy who would stand in front, wield his mighty weapon, kick monster behind, and leave the wizard to take names. Or at least he could be if you wanted him to. What struck me about the 4th edition pregen fighter was that she was on the low end of offensive power. The ranger hits twice as often. The rogue or warlock does twice as much damage. What the fighter is good at is getting in the way of the enemy and she only gets to actually kick monster behind if the monster she is standing next to tries to ignore her. In short, the fighter is NOT doing archetypical fighter stuff anymore. She is standing around and getting hit while everyone else kills the monsters.
