Stone dragon -> Air Pressure stuns require 6m and are subject to the whims of where Air Pressure pushes the rocks.

Unless this doesnt apply Stun Immunity, there is no real issue here.

You can control where the rocks go with Air Pressure by aiming it appropriately.

eh its not the worst, I've had fun as a spell thief stunning them before they got the stun off

That's only if they use just stone dragon for some reason, and no reasonable person will set themselves up for a stun.
