It's only a select few that will be able to tough it out in the big leagues where most of the actual dragons are, and even then you'll probably see more non-fairies using fairy-type coverage moves.
I wouldn't have minded if Fairies JUST had a resistance to Dark, but you're right; giving Dark another weakness was just too much.
