Well, in a social situation, Intimidate can be used to have people doe what you want for an amount of time based on success. And I know of at least one build that lets a fighter use you to beat your friends to death... That counts, right?
Jokes aside, with the Advanced weapon options, and armor options, there is so much more you can do with a fighter. More skills? There's a thing for that.
Fighter is like a martial swiss army knife. Limited only by your imagination on what it can or can't do.
