Is this not exactly the same as in the beginning of the One Piece timeskip? Luffy defeated the Pacifista robots with no effort at all and it was very hard for him, Zoro and Sanji to defeat only one of them together before the timeskip and later on Fishman Island nobody stood a chance against Luffy until he got trapped in that bubble when he was fighting Hordy Jones. I guess that bubble was Luffys nerf. Doflamingo is the only villain after the timeskip that has given Luffy a real challenge. The villains that can give Natsu a good fight will come later. Also its usually only the good guys that get stronger and stronger in these mangas and the villains stay on the same level and never train. Would be pretty difficult for the heroes to get to the villains level of power if the villains got stronger at the same time. The villains usually only get stronger sometimes by using power ups like that Blackbeard in One Piece is absorbing devil fruit powers and that Kabuto in Naruto absorbed Orochimarus DNA for example. That was power ups and not training.
