The team I'm hoping to make in White has 3 out of 6 of them with specific Hidden Powers, so it's going to be annoying. I suppose I can live with the Base Power not being the maximum, though - anything above 65 would do.
No, I don't use the Dream World. I've been meaning to start, though, especially by the time the Arceus event is out in February. Ditto should have won that, though.
