And right there, you have the manga's entire problem: instead of giving villains scaled to a level to where the protagonists can beat them, you have a whole bunch of people who are supposed to be on Gildarts level getting curb stomped by people who are not Gildarts. The villains are too OP, thus we have bull like this.
