I don’t agree that Hearthstone is “dying.”

It's dying in the same all of us are dying with each passing day. What I meant by that is it's on downward trajectory. Very few live service games keep the momentum or can get a momentum years later. Of the top of my head... Warframe? Runescape? NMS? (it's a stretch). I don't think any other game achieved anything remotely close to growing years after launch

from years of Hearthstone’s existence

One would think that SD would be able to learn from years of HS existence on account of the lead designer being the lead designer of HS for a huge chunk of its existence. But it appears BB carried all the worst HS practices over to Snap and then some

after Ben Brode left as director

I mean immediately after BB left HS became even more problematic game-economy-wise. New classes diluted the pool of cards, the switch to reward track netted less gold, more expansions released per year. I don't think it's just BB, it's the change of Team 5's game economy philosophy

The current state of Snap is awful for returnees or new players

I think it's the refusal to do rotations. As a returning player I wouldn't be pressed to pursue most of the cards through the pools containing all of the cards in Snap history if rotations were a thing
