You're description are actually very helpful, so no need to apologize

The system I am using is Exalted by White Wolf, so perhaps a bit obscure (at least the game is around my part of the world), but if you have stuff for that then that would be great!
Oh, well good then! I know of Exalted, yeah. Haven't played it, but I guess it's kind of a different beast to my usual fare. Still, if you want to make combat seem less appealing, do emphasize the brutality, the chaos, the ugliness of it. There's some very simple reasons why real people in real life don't want to get down and dirty unless they have to, and that's the fact you quite literally live by, die by and live with the direct consequences of your actions. Just a tiny little mistake and it could be all over. There's so many other ways that could be so much better.
If you're brutal enough, hammer them down hard a few times if they're too eager to fight. That always works. Hit them and make it hurt. They'll start looking at combat as a more serious thing.
And since this is Exalted, I guess being shot at with arrows is actually relevant! And I've been shot with an arrow (which had to do with a neighborhood bow hunter, the really overkill draw strenght requirements of any bow used to hunt even small game and me being where I really shouldn't have been).
The thing about arrows is, when one hits you, it will punch. A lot. Bullets, at least certain bullets, don't discharge all their energy on you on impact (some are designed to, for stopping power), they go through you and much less kinetic force hits you than is retained by the bullet. But when an arrow hits you, it will punch. The shaft, shaking every which way, will actually enhance that. There's a very strong impact. And there's a certain interesting aspect to it, too.
You see, a strong bow hits with so much force it won't just incapacitate a certain part of you. It will incapacitate you as a whole. Getting hit by a properly loosed arrow will make you fall, unless you take it in the arm or somesuch. The force of impact will simply make your muscles stop functioning for a bit. You'll fall over, even if the shot shouldn't have made you drop. Unless you're freakishly tough or something, I guess. It just feels like this really strong, really painful impact on your body, and suddenly you're toppling down. It makes getting shot with an arrow even more distressing, really.
And blunt weapons hurt in all the ways of their own. In both better and worse ways.
