There is a lot to be said about the RNG inherent to Hearthstone. A lot of the games can be decided by coinflips, outrageous Discovery choices, and all sorts of random nonsense.
You know what’s infinitely worse IMO? Not drawing your cards.
Jesus Christ, I have had some insanely bad luck in the last four games I played. We’re talking getting to the last 7 cards in my deck, which consisted of four mana-ramping cards, the Malfurion DK Hero, Ultimate Infestation, and Jade Idol. As in, I somehow held on and dug through my deck that far, but not far enough for it to matter. If any of those had been closer to the top of the deck, I might have had a fighting chance. Switched decks to Spiteful Priest, then faced the mirror match wherein my opponent hit both his Spiteful Summoners on Turn 6 & 7, but mine were nowhere to be found.
Do I care that his summoned a 7/14 creature that I had no clean way to counter? Nope. RNG is RNG.
What I care about vastly more is how badly my deck(s) have bricked the last half dozen of games. Your opponent top-decking the exact answer they need, or having a God-Hand that kills you on turn 4 is not something you can really do anything about. Your own deck not giving you anything – literally against all odds – is something else entirely. Give me those 50/50 losses over an improbable streak of 10% failures that leave you with no options.
Except, it’s worse than 10%. Seriously though, look at this:
I ended up 14 cards deep into my deck before drawing my first dragon, when there is eight of them in there. According to this Hearthstone calculator, the odds that I should have had at least one in my hand by then is 99.5%. That doesn’t even account for the fact that I mulliganed two cards.
Statistically, 0.5% days happen. But when multiple of them happen in a row, when you only play ~20 games a week… yeah. Let me play against my opponents and lose due to a bad matchup or poor trades. Don’t let me lose to the equivalent of Mana Screw in Magic: the Gathering. That is way worse than losing coin flips, IMO.
