dude dont use the bloodlust with your fighter man.
its prolly whats messing up ur fighter.
maybe the berserking feature of the bloodlust is interfering with you innate fighter berserking ability.

ohh by the way
its prolly a good idea too have ur fighter also have a ranged attack since fighters have no magic.

another good idea for fighters is that they dont have much to do skills wise.
so u might want to take advantage of the extra skill points and dualwield him, as well as make him a good bowman.
I really dont use a shield with a fighter since they can already wear the strongest armor, plus they have so high hit points plus u should be getting iron skin early on also. So u really dont need the extra protection, so might as well use ur other hand for another weapon.
I gots the diamond eyes on his offhand.
