I think they shouldn't have gone from all to nothing. The reward cards are not such a big deal, i think. But because they stopped handing out the free booster packs, a lot of people can't grow their deck anymore.
I would have love to see them come up with a creative solution, like reward cards for daily quests, but if you complete a DQ 5 days in a row, you'd get a free booster pack. That would have been much more fair...
