>>48510127No, it's because a 50% to Special Defense doesn't fix the actual problems that plagues the Rock type. But hey, crawl back to your little huts pushing out strawman after strawman on why it's good for a slow Pokémon like Aggron or Aurorus to have two double-weaknesses because "Tyranitar is in OU and makes its typing work".
Here's a hint:
five weaknesses with three of them being common, type combinations usually resulting in one or two double-weaknesses, moves with piss accuracy, and almost every Pokémon with the type being slow for no reason at all (which wouldn't necessarily be a bad thing if Rock wasn't shit for slow Pokémon)
