Let’s just go by the data - according to HSReplay, DH is the ONLY CLASS with a winrate over 50% right now. Yesterday, we had 4 classes in the 50-52% range, and the other 5 in the 47-50% range, which is par for the course for a solved meta like pre-AoO’s. DH is so good that it has pushed every single other class in the game’s winrate below a level required to climb. When one class has a 58% WR and the next highest is at 49%, that’s a significant problem that needs to be addressed as soon as possible.
I spent several hours watching streamers play at high legend ranks; 75% of matches are DH mirrors. I queued up a few matches myself in dumpster legend with some homebrew pally decks, and proceeded to queue 7 DH in a row before deciding to close hearthstone out and play a different game. Just scroll through the HSReplay DH decks - there are multiple decks with winrates OVER SEVENTY PERCENT over THOUSANDS OF GAMES. That’s unprecedented levels of dominance. Pre nerf Undertaker Hunter or Patron Warrior or Quest Rogue never came close to this.
And that number doesn’t even tell the whole story. Remember, over half the ladder are playing DH at higher ranks right now. Hypothetically, two relatively equally skilled players playing relatively similar decks should have 50% winrates against each other. This 70%+ winrate means the winrate against a normally balanced vanilla class is in the 80-90% range to average out with the mirror matches to give you a 70% winrate.
DH does it all. You simply can’t out tempo it in the early game and will struggle to out value it in the late game if you somehow managed to survive that long. The class has so many options playing against it feels like playing against an adventure boss like the Lich King on heroic.
The deck that performs the best against DH is Gala Warlock with a staggering 48% winrate. Every single vanilla class in the game is unable to compete with DH, even with tailoring your card choices and strategy around an attempt to counter them. And even if it was possible to consistently beat DH by teching your entire deck around it, that isn’t good game design. We shouldn’t have to change the entire way we play the game to beat one singular class. This is the biggest balancing issue in the history of Hearthstone. Skull of Guldan is the best card printed ever, period. DH absolutely needs a nerf across multiple cards to bring it back in line with the other classes.
