This jutsu is primarily a defense jutsu without any damage points. It creates small pockets of air inside a gust of wind to either gather dust or sand on say a tree branch to make it harder to land on or the gather sand in the enemy's eyes which makes it harder to see and causes some pain. Now during my Raiton training, I deducted that this would be a great counter to Lightning Release: Lightning Surge. That jutsu channels raiton chakra through the ground in the form of an attack. The Dust Wind Technique has an elemental advantage of the jutsu and it disturbs the ground which acts as a medium for the Raiton jutsu. It would cancel it out and still go on due to the elemental advantage. Its a textbook counter and pretty much eliminates any reason to argue.
The Jutsu can also act as an distraction. Putting sand in the enemy's eyes is an immediate concern that must be taken care of or else they will lose a sensory organ and experience agonizing pain. While they are worrying about that. A shadow clone can come an attack. The user could too I guess. This can be taken a step further and done at the same time as another jutsu thus decreasing the amount of time the target has to clear their eyes.
