The Shonen mangas mainly do something like this. They originally derived from the Dragonball Z series, which involves power level and full power attacks like the Saiyans for example. Naruto, One Pieces, Bleach, and Fairy Tail carries different themes. Naruto=Ninjas, One Piece=Pirates, Bleach=Shinigamis, Fairy Tails=Wizards. The Shonen category as we all know follows the same action format from The Dragon Ball series. It's not surprising it will turn into something like this.
If you read mangas outside the main Shonen manga, you won't have this kind of issue because most mangas don't follow how other series were written. Shonen again, does follow from another series.
