Now that the shock of the Fairy type has settled somewhat, I've figured I might as well embrace it. Perhaps it will push the dragons down from their mighty throne. Perhaps most fairies will be slower than dragons, and obliterated by the secondary attacks the dragons tend to carry (and still hit hard with). Though, if the rumoured immunity is true, at least it will be easier to stop an Outrage rampage now.
One thing really irks me, though: Kids will inevitably start screaming for Light or Sound or Love types or whatever come gen. VII. Now that a new type actually happened despite the great sceptisism of the community, they definitely won't shut up. "It happened in Gen. VI, so stay quiet!" they will say, then proceed to post proposed stat spreads, modified type effectiveness charts and new moves, names and all.
Also, I guess Vivillon will be the Ledian of this generation: An early fully evolved bug akin to Butterfree or Dustox, but only evolving once. It will probably be the kind of 'mon you ditch before reaching the fourth gym.
