@Demnchi - I don't think anyone said it was only for money, but it will be the primary reason even though they do not acknowledge that at all.

@Maximont, with regards them citing lowering barrier of entry for new players:

1) If there's an assumption that new players want a playset, then the barrier of entry is still incredibly high for only 2 years worth of cards (I never completed Classic and GnG with Ł200 dumped into it and a fair amount of grinding) and the ongoing cost will be huge. This is not about making it cost-effective for new players to compete.

2) If there's an assumption that players don't need a playset to compete, then they don't need to rotate anything because players can pick up cards they need from any set by crafting them. It will be no cheaper crafting specific cards from newer sets than older sets.
