I think this is another decision that will box out and prevent new and smaller players like myself from really getting into the game. The packs are going to sell out, and I'm guessing very quickly. So why not give all players, most of whom are willing to pay retail price, a chance to get in on the action. I think letting newer players get a taste for building a deck of their own will go a longer way to gaining long term loyalty, rather than make them rent to success with cards that only temporary.
I'm hoping I'm wrong though. I'm hoping the packs don't sellout immediately and I have a chance to pick up a few packs and not pay an exorbitant mark up. We'll see soon enough.
