This Greediness debate is easy to argue either way, mainly because the freemium paradigm has become more disparate. Added freemium game modes grows the F2P player-base and the F2P experience (adventures, BGs, DH etc.). Of course, there are many more price points offered around the game now (Passes, Locked Duels treasures, DH legendaries etc.), and the total cost of experiencing everything seamlessly (w/o the annoying gold grind) has also increased.
Forget about nitpicking the dubious rewards track for a sec. As I see it, Blizzard's duplicate protection; their 'significant generosity' towards what was always a dirty quasi-gacha economy, is merely a ruse to enable the mid-expansion mini-set. And if the 35-card set is anything but ALL Commons/Rares (which it won't, let's be real), I only see the economy worsening in favor of Blizzard and the most invested players.
To answer OP's question; many folks may never admit fault (in this case, spending loads of $$$ on a market-dominant PC game). Understandably, it's harder to do so once folks are committed to so many sunk costs, and this would be the forum of all places I guess. I for one, will admit I hated spending $50 on TGT, regret every penny. But I may justify the other expansions I pre-ordered, and the gold I was able to save for down the road. ... But in the long run, my modest pre-orders don't mean sh*t to the grind in this economy. I hope to see you in Runeterra or Cyberpunk!
