That Free to Play mentality that he uses in his series would never work for me. To put it bluntly, I don't want to disenchant any of my cards. The completionist side of me wants to eventually have them all, and disenchanting a card for what amounts to 1/4 the value of a comparable card (i.e. you have to disenchant 4 rare cards to create 1 rare) is just a no-go for me.
Also, not everyone is Trump. Being able to play Free to Play with an extremely limited card selection means that you actually need to be skilled at deck building. You need to know what cards to craft next and what should be replaced. Now, I don't know about you, but that sounds like a HUGE problem to me. Why? Because the people typically trying to go with a Free to Play setup are the new players (not pro-gamers), and there's a good chance that they have no CCG experience. They have no experience, and you want them to be able to determine card and deck viability? You might as well ask them for their opinion on proper MOBA item purchase orders. D:
