Blind Packs suck...and it will make it harder to collect.
However, if the cards as manufactured all in equal numbers, then getting duplicates would actually be easier IF Nintendo provided fewer cards.
I understand the desire to collect everything perfectly, and that blind boosters prevent this...however blind boosters are more in the spirit of the game...and going to buy the exact card for whatever you wanted is not in the spirit of Animal Crossing. So, I think I agree with Nintendo's blind card approach.
