It's not really cheating, since you do end up using all your MP. Which is why it becomes less useful in fights where you need lots of MP, like many near the end of the game. They are really meant for killing enemies very quickly or severely weakening them, which makes it useful for Mark Hunts which would normally be too powerful for you to beat. And it's also useful against Demon Wall #1 when you first arrive at Tomb of Raithwall.
