You should just copy / paste the code for Teleport Strike, change the color to make everything yellow, and put a little MS Paint spear in our hands. Then modify the damage and effects.
Boom, Focused... Strike?
But seriously, I think this bug has been discussed to death. I just don't understand why it has taken two years of tweaking the same spell. Just rebuild the damned thing. Nobody would care if the ability was completely redesigned and the animation scrapped. Well, except perhaps the person who designed the animation.
