Alright, I've seen about two threads complaining them disliking the new Fairy-type. Personally, I like the new type, and even if fairies are mostly associated to girls, doesn't mean boys can't be Fairy-types.
Now the Dragon type only had two weaknesses. With the Fairy-type, it has now three weaknesses, with this type of move doing super effective damage.
Also, when Generation II was introduced, certain Pokemon Magnemite changed from Electric to Electric/Steel. I don't know why so many people are making a big fuss out of it. Just deal with it, since the type is there now. :P
