Oh since we're talking about Stinger, make its predicted shot shoot at where it will definitely hit the current target.
In this example, where the circle is a fast unit and the arrow the direction its moving, make HLT shoot the GREEN dot instead of the current RED dot. There's no reason to be shooting the red dot. I understand why it's done technically, but the logic behind it is fault and doesn't make any sense. The green dot is a far better point to be shooting.
