Well, being an elder dragon is a cheap excuse.

But, I think Kushala being able to control the winds is part of the reason for its strenght. I always tought the wind control was some kind of psychic power, which the Kushala uses to control the air around it, it also seems to use it to propel itself when charging, and since its body is made of sharp metal I guess it would hurt a lot to get run over by it. The metal skin is a better excuse than the Elder Dragon one, and really, Elder Dragon became a buzz word for anything that is unexplainable or misterious in the game.

I guess it is the animations that are to blame on this one, Diablos moves too fast and makes too little damage for what looks like a killing blow, while Kushala, in an attempt to make it move with grace, moves too slowly for the ammount of damage it causes.
