Didn't Thor beat Captain America while powerless? And Didn't thor beat Seth (A god) with only his fighting skills? I'll post the actual description on the page itself.

"Master Combatant: Thor is a superbly skilled warrior trained in the arts of war with over countless eons of combat experience. He is one of the most skilled fighters to ever walk the planet. He has been able to fight and gain the advantage with Captain America when powerless to the point he was mortal, and he was able to defeat even the likes of Grog the God Crusher, while similarly powerless and mortal, with only his vast fighting skills[43]. Although, he possesses vast fighting skills, due to his warrior pride, when engaging opponents such as the Hulk, Juggernaut and other brutes in hand-to-hand fights, Thor reverts to using the same brawling type fighting as they do, in which he is also a master. He is a master marksman, and master in all areas of combat including hand-to-hand, wrestling, brawling, swordsmanship, hammer throwing, mace wielding, and more. Thor is also very well versed in all the ancient fighting arts of the ancient Vikings, Celts, Saxons, and the Germanic tribes of ancient Europe. Being a War God as well as a Thunder God allows Thor to learn and master nearly all the martial arts of Midgard as well. This gives Thor a huge advantage in combat by tapping into a vast multi-cultural perspective of combat arts, skills, strategies and tactics. He has also shown great skill with numerous other weapons such as axes, shields, and clubs. Thor is known to be very cunning and intuitive in battles and wars."

From that description, it almost makes it sound like he should be higher in fighting skills.
