I've played with sticks a lot.
Do you hit people by thrusting your arm forwards? Do you hit people by punching your right arm from the left to the right? Upwards and down? It results in slower and weaker movements, and more predictable. Yes, blocking is easier. The goal isn't to merely hit with the sword at one place, its to hit and drag it onwards, to slit, say, the entire stomach up, instead of just cutting deep in to the flesh.
I hate to break it to you Uzor, and I also hate to further this derailment (so this will be my only post on the matter), but Ruffy's right. The way NIN holds the blade in FFXI is not a particularly good stance. It's incredibly weak on attack, restricted to poor reach and using fewer and typically weaker muscle groups than more traditional methods. If you want to hit with any power, you have to bring the blade in
closer to your body as you strike, and an impact on anything solid has a much higher chance of jarring the blade from your hand simply due to the way the human hand is formed.
Its sole virtue lies in the fact that it IS unusual, and if you're willing to risk breaking your weapon and/or ruining its edge, provides for slightly more strength on the block. Other than that, you're much better off holding the weapon in a traditional "blade up, edge out" stance. You'll have much more reach and flexibility, and while you won't be able to parry quite as strong an attack, you also will be parrying
properly and not like a dumbass that wants to replace his weapon every fight.
If the weapon is held facing down with the edge facing the arm,
that's a power position for slashing and stabbing. It lacks flexibility, of course, but it makes for a nice reversal slash in a knife fight particularly. Tricky to master the grip switch though.
If you're looking to attack with primarily light slashes against an unarmored opponent, your
still better off using the blade in the conventional grip. Differences in strength are largely negated against someone who's not wearing any armor, true. But if you are also unarmored, he's going to carve you up like a freakin' turkey from about, say, the length of your respective weapons
outside your reach, since you're holding your blade like a "Oooh, scary Ninja!" He'll have twice as many angles of attack assuming neither of you changes grips. He'll have better overall defense, and his parries against you will probably not involve your blade at all, rather choosing to remove your hand at the wrist since that's about as close as your blade.
In short, watch less anime.
