Countdown is correct, you don't have to attack anything unless you are a Frenzied Berserker or the like, or possess any sort of feat, ACF, or PrC ability that would require you to attack someone.  You just can't focus enough to very "smart" things.  You still make a nasty fighter and can smash through enemy lines, but no crafting, spellcasting or picking locks... you'll just smash the door down or bust the lock.<br/><br/>And say the hell with stealth.
