Is he a new player? I'm trying to figure out if he has a plan or just making choices as the game progresses. From what's been described, it sounds like he's trying to build something "balanced" without being tanky. If he was deliberately sabotaging himself, he wouldn't have started with two strong fighter feats. If he has a particular concept in mind, he may not be averse to suggestions that support it.
On a 15 point buy, a human fighter can have five 13s and a 12. No real clues there unless you used a higher point buy.
Known feats are Power Attack and Furious Focus. With Toughness, his hit points should be decent (around 23). What other feats did he choose?
Assuming he's spread out his skill points the same way he did his stats, I'd guess he has at least a point in 7 class skills and a couple in Perception. So not a skill monkey but definitely not a slouch.
No armor or ranged weapon. You mentioned he wasted a few rounds closing with the enemy so he doesn't sound not overly cautious. Has he given any in-character reasons for not gearing up? Not knowing anything else, I wonder if he has a more relaxed playing style or if he's oblivious on how his decisions are aggravating you.
