Now that we’ve had the Fairy type for a while, how well do you think they achieved their conceptual goals, which ostensibly were to both nerf Dragon Pokemon and re-assert the offensive relevance of Poison and Steel types?

Pretty well, I guess?  A lot of Dragon-types are still really good, but they’re largely carried by their extremely high base stats now; the game is noticeably much less about throwing Draco Meteors and Outrages while blocking with Steel-types than it was in generations IV and V.  You can’t really make a competitive team with, like, four or five Pokémon from one of those two types and expect it to work, which… you arguably could, for a while?  You still probably wouldn’t stick a Poison attack on a non-Poison Pokémon unless you were really strapped for better options, but I guess I feel less bad about using Poison-types in offensive roles now.  Steel as an attack type often still feels redundant with other attacks that a lot of the same Pokémon tend to learn (and when do you need a type advantage against Ice, anyway?  They don’t resist anything; just hit ‘em with whatever), but Steel Pokémon are fine, obviously.
