Fellow Hunter and Rogue players, you don't have to be worried about this nerf — because it's not really one. Obviously, you know well that your main classes are currently dominating Hearthstone Arena Mode, and perhaps you feel that Blizzard is going to strike your favorite cards and decks with the nerf hammer.
Well, keep calm and chill out, because the only thing that's going to change is the choice of cards. Hunter and Rogue will see fewer 'good' cards appearing when building their decks, while Shaman, Warrior, and Paladin will on the opposite see 'better' cards popping out. Warlock and Mare are not affected at all by these changes.
The current card buckets can be viewed on the Arena Rules thread here.
