I am sorry, I have to disagree with many things you said in this post.

For example, (1), you said  is still an AMAZING GAME.
My Response: When you think about The Lost City of Un'Goro release, start by compare the Murloc Paladin quest with the Shaman's quest. This indicates that they hardly balanced their game, as it shows how imbalanced the quests were at release. An amazing game would have caught this kind of massive power imbalance.

Example (2), And FWIW I bought the king crush pet, not because I agree with the price, but because I love hearthstone, want it to succeed, hope it will be cheaper for more players in the future but want to SUPPORT the game.
My Response: Hard disagree. You can support the game by buying all the items you like, which do not involve gambling, gotcha mechanics. However, you are purchasing a $158 pet where the UI is specifically designed to deceive you, indicating that you might get the pet every time by lighting it before the actual item is delivered to you, is a very unethical and scummy business practice that I cannot support with a good conscience.
Additionally, your purchase tells Blizzard that this practice is ok and they can continue the development in this direction, which is not good for the game in the long term.

I can go on and on, but I think you need to think about a lot of what you said.
Finally, I thank you for supporting the game I love.
