That was.... Meh... I'll fill in the blanks. ;_;
Ok, wind is extremely good within its own aspect, it is fast, precise and has a tremendous cutting power. Something you did not mention was that wind can be found naturally around at ALL times. When using it in combos, Wind adds to the element used before, or so to speak. So when using wind with a fire, the result will be a stronger, and more largely spread Fire. With the water, the wind can be used to increase the speed and sharpness like weapons, and in some cases when the two are combined it can form a vortex, which is actually also an A-rank jutsu we'll get on to later on.
Wind can also become Sound, when mixed with Lightning. The basis of wind particles utilized with the vibration from the lightning produces waves of Sound. Furthermore, you partially got the strengths part right, when in comparison to the basic 5 elements, this means that:
A rank Wind > A rank Lightning
A rank Wind = S rank Lightning
Vice-versa for Fire.
A rank Fire > A rank Wind
A rank Fire = S Rank Wind
A rank Wind = A rank water
A rank Wind = A rank earth
When it comes down to wind verses earth or water, It's usually equal to it, but as with every jutsu, the effectiveness depends solely on size, shape and affects of each jutsu.. For example, you use the A rank wind blade vs An A rank earth wall which is both tall and wide... That wind won't have enough area of effect to damage the entire wall, instead it'll simply affect the point it hits; though it could end up crumbling the entire wall if you hit it in the proper places..
When in comparison towards KG's and hidden abilities, this is Wind's Strength and weaknesses:
Strengths:
- Rain
- Storm
- Boil
- Bugs (blowing/slicing them away)
- Steam
- Sound
- Shikotsumyaku
- Paper
Weaknesses:
- Dust
- Blast
- Dark
- Ice
As you can see, Wind is generally an extremely powerful element, due to its speed and cutting. And for a final philosophical view, know that Wind is all around us. Just like the Earth, and like I stated in my own wind training; in the narutoverse and rl wind is always present around us. So keep that in mind. Hence you can use that towards your advantage, that is when I believe Wind can be considered versatile, changing the terrain towards your advantage. You can form a wall of wind that blocks kunais and incoming objects of a not so great density, and use the wind to push yourself or your opponent from your previous location towards another one. For example; going airborne, and this can be applied towards objects as well, however we will go into this advanced detail further on in your training.
Now, getting into the practical point of view, get into a meditative pose and begin to concentrate on this new found Wind chakra. Begin to channel it throughout your entire body and into the air that is around you. I want you to feel and become one with this nature as we train..
