This change is great. They actually changed the base stats of pokemon across the board with their formula of how they compressed their version of "Attack" and "Defense" stats from the main pokemon series Attack, Special Attack, Defense and Special Defense. So in actuality they didn't really "nerf" much they just made pokemon that were absolutely useless in Pokemon Go that were absolutely awesome in the main games now actually awesome again. Honestly this should've been the way the game launched but whatever.
