We Learn Nothing New About Card Pack Drop Rates
A new set of rules in China that became active on May 1st requires that games with "loot boxes" publish their odds publicly as to let consumers know what they're getting into. There was a lot of hype surrounding this announcement of these rules because we'd finally learn the deep dark secrets of Hearthstone's card packs, but that's not what happened.
A blog on the Hearthstone China website came out and had this to say about card packs.
- You'll get at least 1 rare, or better, in each pack.
- An epic will be received, on average, in 1 of every 5 packs.
- Legendaries, on average, will be received in 1 of every 20 packs.
- As players open more packs, the actual probability of opening cards with higher quality increases.
TADA! We learned nothing new. Over the past few years, the community itself has done a better job at figuring out the various card drop rates, and even figured out the pity timer. You should check out the card pack statistics page on the Hearthstone Wiki.
Blog Post Translation
Google Translate to the rescue! You should be able to get the gist of it.
Interestingly, the post has been backdated April 2nd. We're assuming this is because they didn't want it to be on the front of their blog and thus widespread knowledge to more casual fans. Fun.
Quote from Blizzard
According to the relevant national laws and regulations, "slag legend" is now the probability of taking cards to publish, as follows:
Note: "slag legend" card package a total of five cards, including four different quality.
Each slag card package, at least to get a rare or higher quality card.
An average of 5 slag card card package, you can get an epic quality card.
An average of 20 slag card card package, you can get a legendary quality card.
In addition, it should be noted that: with the number of cards to increase the number of packages, players actually get high-quality card card probability will also increase.
