Even if the devs or designers would be changed everyday, you still wont be happy for something, thats for sure. Just play the game, enjoy it, and let them do their work. They even dont see those comments, because they are tired of listening some mad ppl, saying all the time:nerf buff nerf fire fire replace nerf nerf. My friend I know you want all decks to be 50-50 win ratio,but you also know it can not be done precisely.
Also not mentioning if one of your decks will be OP one day, you will not ask for a nerf, as you would do for an opponent deck, as you will always have opponents, as you will always complain.
Just Enjoy mate
