Adding Jump Kick for the extra lols. 
Spring Attack is some pretty nice aggro control at the start of a fight. Can reduce the alpha, and make sure the whole mob knows you are there. Not sure I can fit it in on all my tanks, but I'm trying to figure out some ways to do so. My Shield/SS will like the extra AOE, that's for sure.

This would really just be for cute if it works, but does anyone know for certain if Spring Attack will work while in Granite? Since it is apparently actually an animated teleport I suspect it does.
It might be fun to make a 2nd or 3rd build just to see the rockpile hop.
