When people warned blizz about the pruning and the legendaries I think blizz knew what's gonna happen, but they were like money > gameplay. Many people did not enjoy the farming but they did it anyways for various "social pressure" (look it up) reasons, I think this is a serious problem when someone creates a game that they KNOW for a fact will get people in miserable position, but they just do it anyways, because that brings the fat dollars. I stopped raiding and basically playing, but many people stayed and farmed obsolete emissaries and farmed mythic dungeons after mythic dungeons. Then the "flop" with the 4 max legendary drop limit. Ouch. That really says something about the devs. Of course it's easier to play the "wait, oops, we didn't know, but we've learnt from it, pinkyswear " card. A lot of non-dev people pointed it out for them, like seriously a lot of ppl, it was basically a no brainer.
I'm no surprised that the communication from the players is what it is... There are a lot of little... "things" like the mentioned above happening in the game. Maybe some people don't realize it... Or not in the grand scale. Or don't care, which is also fine.
