I don't think humans do not need anything else but themselves, far from it. What I was merely saying was that fighting without the assistance of weaponry was the way that it was intended, and would be the most honourable way to engage. Much like the animals of this world humans most likely had to engage in combat with brute strength and nothing else...that's all I was saying there. It's not my opinion that humans need nothing but themselves, just me merely saying that it's what's considered the 'proper' way to engage, if you get my meaning. However, in regards to the discussion you two are having I would say that using a sword is not cheap...exactly. Guns are, IMO, but not swords. As was said, it takes a lot of skill, patience and strength to wield a sword and for that reason alone I would say that using a sword in a fight is just as accesptible. It could be considered cheap because of obvious advantages one could assume tips the battle in there favour. Yes, swords have range, but I'm sure a skilled enough fighter can evade effectively. Swords are hard to wield and normally if you miss you can become vulnerable for a few seconds. Yes, swords can kill faster. However, like R.Y.A.N.O stated, it is also possible for a fighter using his fists to kill someone quickly too: snapping there necks for example. There are also many ways of crippling an opponent. Swords have evolved into a style of fighting so it is not cheap. They demand as much as those that use there fists. Unlike guns, in which you could possibly just spray bullets, swords require more patience and concentration...even against a weaponless opponent. Sword-wielders can become just as vulnerable with the most smallest of mistakes and this makes it just as intense.
I do think, personally, that fighting without weapons would be the best thing, though. It's a much more pure fight There is no advantage or disadvantage, which equels no excuses.
I hope that all makes sense.
