I've finally realized the real problem with fairy type. It's BORING and it ruined types that were actually interesting.

Fighting had Hammer Arm, Drain Punch, Focus Punch, Mach Punch, Close Combat. Lots of moves with different effects.

Dark had Pursuit trapping and Foul Play.

And Dragon had Outrage and Draco Meteor.

Meanwhile, fairy only has Moonblast, Hyper Voice and Play Rough. They don't really do anything other than deal damage. There's no instrinct attribute to a fairy type that you have to keep in mind. Boring. Awful.
