Why dragon "needed" to be nerfed? Yes a lot of them are strong but that doesn't make the type cheap. Water and Steel dominate way harder. Dragon was designed to be strong anyways. And if you're nerfing dragon because of Psuedos isn't that give Metagross a non dragon psuedo an advantage. He gets to keep the all mighty 600 BST which is not unheard of in non dragons at all.
