People need to stop complaining about nerfing cards, It's really annoying every time someone loses to a card they complain about nerfing it. Blizzard either needs to treat this like a card game and refuse to nerf anything or treat it like a video game and eventually homogenize every class into some always viable paste of blandness like they did with WoW.
If they keep a two release a year schedule of one solo adventure then one expac they can change the format how ever they please they don't need to change fucking cards because F2P trash can't afford Dr.Boom or Healbot makes "Warlocks OP" just make cards that counter those cards and eventually *gasp* after 2 or 3 expansions the card pool is big enough that you'll always have an answer for a commonly played card.
Blizzard needs to hire some fucking WOTC peeps or the dude's from Upper Deck who ran the WOW TCG and fire Mike Donais Or Fucking HIRE BRIAN KIBLER the dude who designed the original WOW TCG and plays FUCKING HEARTHSTONE ALREADY to help design cards for xpacs.
The simple fact is unless the card was obviously a mistake (Skull-Clamp, Jitte etc) then you don't nerf it you just help fix the format by adding more content that helps counter it.
I"ll give you all an example of what I think is a "good" card,
Hungry Crabsits unused or disenchanted immediately because Murlocs are not played but if Murloc agro was played as much as hunters are Hungry crab would be included in a lot of decks as a bullet versus that deck.
Lots of cards now don't have counters because the game is so fucking new that it hasn't had time to develop yet people should not complain about nerfs they should ask for more expansions. It's not fucking hard to design sets, Magic releases and distributes sets every 3 months and that's a psychical product.
If they keep releasing imaginative cards every set eventually you will be able to identify a deck that is dominating you and search through your extensive library of card for an answer to that deck.
My main example for this line of reasoning other than my years of playing almost every card game under the sun some to a very competitive level is
Novice Engineer.
Back in closed beta Novice Engineer was played in almost every single deck and was a 1/2. Apprently, Blizzard saw this card being played too often and made it a 1/1 because it was two "powerful" at 1/2.
Right now Novice Engineer sees VERY little play at 1/1 and it would see only SLIGHTLY more as a 1/2. What's a 1/2 going to go against a turn 1 Undertaker? The truth of it is that if they had done nothing the format would of moved away from the card on it's own and maybe the card would still be played as a swap in option with Loot hoarder. The card now is unplayable due to knee jerk nerfs by a complaining uneducated player base who complained about "cancer" and "Overplayed" cards and decks.
Sorry for the rant, I just really enjoy Hearthstone and if Blizzard gets their shit together they can make this a truly competitive E-sport that I would like to be involved in.
I have a list of the 10 things I'd like to see changed/added in HS that I was thinking of submitting to one of those HS fan sites but It's pretty much impossible to get any type of headway unless you stream.
Edit: And I've met Mike Donais who is the head designer of Hearthstone and in charge of a lot of the "Balance" we see for the game. The dude is a fucking hack and everything he made for WOTC was poison and crashed and burned. He's also one of the dudes responsible for all the new "New player friendly" changes to D&D that basically turned it into a hybrid card game/mini game.
