Excellent display of knowledge, a very quick, precise and specific reply. But, you have forgotten a few things. First and foremost, arms or weapons which you use, can vary very much in distance, and not all of them can only be used in CQC, as you have seen many times, not only in the series, the usage of chains which still can be controlled, unlike a projectile weapon, is very useful not only in closed quarter combat, but even in longer distances, as it was demonstrated to us from Obito. Another thing which you maybe forgot to mention are ninja tool which require the chakra of a person, which are called chakra blades often. First showcased by Asuma, we have noticed that they not only increase the versatility, sometimes even their reach.
Another aspect, but left more untouched, are parasitic, organism as weapons, which we only have one real example, Samehada. IT is a living being, whose versatility is quite powerful and on par with other techniques, but over that, they can actually have added functionality, in Kisame's case, it was the strong chakra absorption, and the merging with it.
Angle and direction of Ninja tools
These are the realistic aspects of the RP. We will be covering one at a time starting with Angle. These are some of the things you need to keep in mind when fighting in a battle.
Angle is a very important part when battling and if used right it can give you the upper hand over your opponent. It's very important to understand the angles in a battle. This is mainly used with ninja tools (shuriken, kunai and other projectiles) but you can also use this with certain techniques that are launched at your opponent. Just by stating the angle you can confuse your opponent.
For example:Ninja 1 and Ninja 2 are fighting. N1 throws 2 kunai at N2, one at the angle of 25 and the other on 55. The lower the angle,the faster the projectile. Most new people would say:"I intercept the kunai with one of my own, blocking them both." If you use angles, this is where you can score.
Here is a pic for reference:

If N1 threw the kunai at an angle of 25 first your opponent would probably be defending from that one first thus he would fail to notice the other one. If he blocks the first one then the second one would hit him unless he kept his focus. Thus with one blow you can cause fatal injuries. (Credits to Cobalt).
