>>41723126well fighting and dark types were also dominating the meta, but i think they just wanted to make offensive fairy more attractive (even though it hits almost the entire type chart unresisted) besides just countering dragon. Classic hilarious GF balancing. Dark did get buffs against steel as well though.
Also dragon as an offensive typing has been basically deleted from the game. The gimmick was it hit everything for neutral, now its basically worthless because of fairys.
