EDIT: @WiselWiselman, the point is that the system is broken, and they felt it needed a reshuffle. And strength has almost no relation to how effective you are in combat with a sword. Give the worlds strongest man a sword, and pit him against someone that has skill with a sword, and the fact that the strongest guy in the world can swing his sword harder will not help him survive. They superior swordsman will win, hands down.
EDIT 2: @ poster below me. I know you're gaining
Two fith degree black belts are fighting. They both have the same training years and same skills. I'd expect the 6'0 200 pound black belt to beat the 5'5 130 pound black belt, because he may be a tad bit stronger.(strength) I wouldn't expext them to hit with the same force. F=MA
Same with a level 40 nord with 60 skill in sword. And a level 40 high-elf with a 60 in sword. I'd expect the nord to exert a little more damage in his swings.
