How i performed it
Sasuke starts to build his chakra channeling it to bus right hand palm, sasuke then brings his hands together to form the rat hand seal, simultaneously using nature manipulation to transform the chakra in his right hand palm into wind, sasuke then releases the wind chakra from his palm, then using shape manipulation on the wind as its released from his hand, sasuke forms a wild wind current, and then sasuke thrusts his palms forward releasing the wind current and also releasing a constant amount of chakra as the wind current travels through out the battlefield picking up little debris as it moves further.
Advantages
It blocks eyesight, its also capable of being a defensive jutsu, since the jutsu first states that the wind is released from the palm of the user, it believe it can be a good defensive jutsu against most lightning attacks.
Disadvantages
With the amount of air current happening and all it picks up, one would think it would have enough force to push back the opponent atleast/damage him in some way, but it does not but block eyesight.
your counter
You counter would kill me, well first it would kill the air currents and then come at me, with a lesser rank but still with enough heat intensity to evaporate me .
The Speed Rate
I'd say medium to slow, medium because of the formation of the hand seal, building chakra releasing it, shape manipukation to create the air currents, "to slow" because of the stretching through out the whole battle field.
