I think it's really smart. I'm a serial LCG player (Netrunner, Thrones, Arkham, LotR, Doomtown, Ashes if we're counting that...) and the worst time to be playing, for me, is that post-launch period where the card pool is tiny and the deck building options are extremely limited.
I didn't start enjoying Thrones until about two cycles in and decks stopped being some variation on "good stuff". I still don't like Arkham as much as I want to because the player card pool is small. Accelerating through that staid launch period is a great idea.
