The most unusual and unique thing happened to my shamans when I clicked my formation macro. I have NO idea if I clicked something else in the process to cause it or not.

The formation macro was that a diamond:
....X
X.......X
....X

When I hit the formation button, the two in the middle who held the outside suddenly started running in large cirlces around my main. Problem was, while interesting, I couldn't stop them from doing it. I had to eventually log out to get them to stop; so I placed it as a glitch.

My question... is there a way to get your characters to run and circle a target like they did? I'm thinking that would be a kick ass method to handling moving enemies if so? Or... was it simply a glitch?
