^ Except water is much, much denser than air, making it pack much more of a wallop if you're hit with a blast propelled at high speed. And Waterblight is explained as water getting into the hunter's lungs and making it difficult to breathe.

Wind could be used because a couple of monsters already use it at a high enough pressure and force to cause physical damage (Kushala's tornado and Najarala's sonic blast). But it probably would be tricky thinking of different ways for monsters to utilize a Wind element, and thinking of what Windblight would do.
