Or Titan/Bismark/probably Sephirot and jumping off the edge! Seriously, I misclicked it atleast 6 times doing Bismark Ex when HW came out.

I'm about half and half for using it for aggro and using it just to jump around. In fact I just used it yesterday because a tank decided to stay out of tanking stance too long and I was drawing in a lot of aggro during some of the trash fights, and let me tell you, Banish ain't fun to get hit by constantly when other adds are on you.
