@LuffyxNami00 Do not be so butthurt, dude. We are at chapter 51 and it keeps repeating all Fairy Tail's trope i've seen. First, Acnologia was overwhelmingly powerful, now suddenly there are many more dragons stronger than him because 'logic matters', right? Same logic as Alvarez Arc, where Natsu & Co got a huge power boost, as he one-shotted Bluenote, and suddenly there were much more powerful enemies, as Spriggan 12.
'ThE fOmUlA iS cHaNgEd' so much that the Water Dragon has been defeated because the Fire Dragon gave Natsu a power boost. Well, Oración Seis arc for you. Almost whole Fairy Tail was defeated be a single enemy here. Now, the same has happened in Alvarez arc by Jacob Lessio. What happened after? The enemy is defeated and the other members are saved.
If 'ThE fOmUlA iS cHaNgEd', then Kiria would've killed both Erza and Laxus when they were down. Wendy would not have received any ass pull powerup from a defeated enemy and so on.
But if it perfect to you, go for it. Do not be so mad at some comment made by some random internet person like me.
