There is no second thought that fighting styles are not balanced. I'm not even going to mention how ridiculous is trying to utilize unarmed and one-handed. 2h is leaning in that direction. While you can make good things happen with it, it's mostly sub-par to 2wield or ranged. Let's just compare 2h swords to bows since there won't be an issue of ench/charm slots there. You can max out battle fury (and while it looks great on 2wield) while a bow user has the awesome way of the ranger. That alone is 300% ahead in damage. Maybe you can try and go for thousand strikes, but even if you had the mana pool, you'd still be better off stunning and aoe-ing from distance. There are no classes here - a bow or magic user would not have less hp than a melee character does. I don't see how a swinging arc and a slight increase in range balances 2h swords as a weapon or playstyle.
