>>55655732It was an overreaction of the Gen 4 and 5 meta post Physical/Special Split.
Defensive Pokemon in Gen 3 and back could just be bulky. Reliable healing was not a baseline requirement to be a defensive mon, because your weaknesses could be entirely absent from one side of the physical/special split. There was no way to hit, Skarmory or Milotic super effective on the physical side, nor a way to hit Ludicolo or Blissy super effective on the special side. That means mixed attackers were really the only way to be a true wall breaker, and they inherently had more weaknesses because their stats were spread so thin.
Come Gen 4, and defense borderline does not exist anymore. Your game state is considered advantageous if you are down a mon with Stealth Rocks, because your offensive pressure just got better. Then with non-legendary permanent weather in Gen 5, and defense completely collapsed.
So, Gen 6 added Fairy, a great defensive type that requires traditional defensive types to answer to, and insanely upscaling massive defensive abilities to provide defensive pokemon free resources, like Unaware or Regenerator.
Now, even though the defense and offense is more even than gen 4 or 5, defense is so much more annoying to deal with, since they don't have to work to recover or try to squeeze in Encore/Haze/Roar user to ignore a set up sweeper. They just get all that shit for free.
