It's power shot/myth move/scare tactic. I don't mind if I get to wield it only in MFN-# leagues figuring the more competitive types figure it out here in private leagues.
But I do find it funny when I catch a Tosu or King of Bling with it after they popped off at me, therefore, it's a way for me to strike back. :)
At the very least this loophole is not a secret and is available to anyone. My endgame is to make everything fair as possible, which is why I opened this can of worms in the first place.
