Lol, I completely forgot about hearthstone. I stopped playing it when Grand Tournament came out. Every single deck was the same, it was either a pally secret deck of everything you do benefits me-ness or a murlock deck that unless you have 6 AoEs in your deck you don't even have a HOPE of beating or some other OP crap that I just couldn't get the cards to make. And I don't want to play a card game where a custom made deck isn't useful. The only decks used were all pulled from the internet because they were the best decks period. Nothing else could beat them. And I didn't want to make one myself because A. I couldn't get the correct cards EVER and I hate disenchanting my cards because with a card game I always feel like the object of the game is to, you know, collect cards. And disenchanting was very inefficient in that manner. and B. I didn't want to be just as uncreative as they are. The point of a card game is to strategize and make your own decks with whatever cards you happen to get. That and there were way way way way WAY too many cards that have drastically random effects and if I lost I almost never felt like it was because I played wrong but because I was simply unlucky that both of Dr. Booms bots did 4 damage to my hero when I had a full board and killed me.
The only enjoyment I get out of it anymore is the tavern brawl because it's mostly SO ridiculously random that I don't even care whether I win or lose. And I do enjoy the raids but I can't get enough gold to unlock them without playing the actual game which just enrages me like no other. And even if I do subject myself to the torture of trying to complete my quests I never can because if things even look somewhat bad everyone just surrenders and I can't actually deal damage to their hero for my deal damage to heros quest! And then I finally complete my quests after days upon days of torture because it takes 700 freaking gold to unlock the next phase of the raid, and I get about 30min to maybe at most 2 hours of fun gameplay trying to strategize the best deck to defeat the boss and it's heroic version. However, most of the bosses I can defeat with my warlock mech deck anyway, so, yeah. It's just not worth it.
That and they nerfed my favorite beast hunter deck by making the starving buzzard literally a worthless card which should never ever even be thought of using.
