Ah, unfortunately, you are wrong.
Let's take my sensei test as an example.
In the first or second move I did, I happened to use the Plateau jutsu, and why?
First off, it gives you a more elevated eyesight of the entire battlefield. Second of all, since you're above the enemy, you can't imagine how many more advantages that gives you, one being able to use the force of gravity. Furthermore, since you are no longer at ground height, projectiles take longer to reach you. You can also avoid more dangerous jutsus like antlion or basic wind and fire attacks because of the solid elevation.
Ever thought of all this?
