I kinda like Dark the way it is. 2 strengths + 2 weaknesses = balanced! So I hope Fairy n Dark are neutral against each other.

I think Poison type should be strong against Fairy

its a long read, but definitely worth it, just too point out at a demo(gamescon), it was confirmed fire types resist fairy, which is wat this man posted months before fairy type was revealed http://pokebeach.com/2013/06/pokebeach-x-y-rumor-roundup-and-clarifications

Dark Type is the Best Type!
