@Redcrow: Thats #3 on my list. its certainly a potential solution, yes.
Really the big thing that bothers me is that the 2wpn style includes the 1wpn style and more. the guy with sword and board is just as good at fighting without the shield as the guy who has focused on fighting without a shield; when you'd think the guy with the shield would be used to a different stance, posture, and set of moves, and wouldn't be nearly as good at fighting without something in his off hand to deflect attacks; whereas the 1 wpn guy has been training specifically to accomodate those restraints. he knows to turn his body sideways to minimize the target more, and he's better at doing it. He's used to fighting at a much sharper angle than the guy with something in both hands, and should be better at doing it for that reason. The guy used to having a shield is going to be off-his game, and at a disadvantage.
The shield guy probably wouldnt be as good of a swordsman, but he's got the shield as well, and the skill to block with the shield when its there.
Should Sword Only be as good as Sword + Shield? Likely not. No.
Should someone who trains to use Only a Sword be better at using Only a Sword than someone who Trains to use a Sword and Shield? Pretty sure yes.
That could be accomplished this way, with separate skills, though it might be too harsh and you might be too crappy with sword and shield together in game.
It could also be accomplished via the penalty when using only one item in a combat style. A Penalty the one-sword guy wouldn't have.
@Rust: I suppose you can take the approach of "tough shit, you learn what's available." I'm going to go with the assumption of 'lets say theyre already successful mercenaries, or belong to a mercenary guild where they can afford to pay for training and equipment for whatever fighting styles they might want.'
And regardless of what styles are available, if one style includes all the techniques of another style AND its own techniques, shouldnt that style take more effort to learn?
@Halforc: You make a decent argument for your first point. you are better off with a shield (or an off-hand weapon) thats very true; just like you're better off in boxing if you have two arms. That makes me not sure about the idea of making them separate skills. That may be too harsh on the sword+shield guys, and too easy on the 1 sword guys.
But your second point seems to be missing my argument and going back to "weapons used" instead of "weapons trained in use". Why would the guy who is used to having the shield be just as good at fighting without it as the guy who has trained to fight without it?

I think maybe this rules out the "give them an extra CA for evading."
So now I could use some help deciding between these two:
1. Price "Sword" Cheaper (double the points for the same cost) since its effectively half a combat style, so the people who train in it are better with swords than the guys who split their focus. Bonuses: Only tampers with how 1h styles work, and they'll be happy it makes things easier for them. Its easier to start with really high scores this way though.
2. Price them the same, but when your fighting style is partly missing (sword and shield guy fighting without a shied) you take a dice penalty.
