There is some re-balancing in the next patch (they mentioned the level effect on combat, at least). Presumably it will be released near or at the same time as the
add-on (about September).
If every weapon skill was equivalent, then there wouldn't be any point to having different ones. As it is now you can choose to use the 'best' skill early in the game, or with your first character, and then pick something more challenging later.
