Is a bug effecting drop rates?

Players on Reddit are reporting a higher than anticipated drop rate on the new tri-class cards such as Grimestreet Informant and even legendaries like Don Han'Cho.

"Looks like there is a severe bonus chance to open the commons for each gang. In 50 packs I got 7 Kabal Chemists, 11 Jade Spirits, 11 Grimestreet Smugglers," writes maskdmirag. Another user reports getting more than nine Jade Spirits in only 20 packs.

Blizzard has since made a statement saying, "We are currently aware of reports of players having a higher chance of opening tri-class cards in MSOG packs and are looking into it."

Update: Blizzard has issued the following statement.

Greetings,

After the launch of Mean Streets of Gadgetzan on the Americas server, we discovered a bug with Mean Streets of Gadgetzan card packs that unintentionally made the drop rate of tri-class cards higher than intended. We apologize for any inconvenience this has caused.

A hotfix was rolled out to all players on the Americas server at 2:30PM PST, which corrects this issue. Players on the Americas server will now see tri-class cards appear at a drop rate that is consistent with other cards of their rarity.

Any player on the Americas server who opened Mean Streets of Gadgetzan packs before 2:30PM PST will receive additional Mean Streets of Gadgetzan packs as compensation. The affected players will receive 33% of the total amount of Gadgetzan packs opened before 2:30PM PST, rounded up, to a minimum of one, regardless if the player acquired packs through gold, Quests, or real money. Since cards are generated upon pack opening and not pack purchase, packs purchased before the hotfix but opened after the hotfix will not experience this bug and will not be a part of the compensation roll out.

For example, if a player opened their 50 pack pre-purchase bundle before 2:30PM PST, they will receive 17 additional packs. (33% of 50) If a player opened one pack of Mean Streets of Gadgetzan cards and completed a Quest that awards two packs before 2:30PM PST, they will receive one additional pack. (33% of 3) If a player opened 47 packs before 2:30PM PST, and 23 packs after 2:30PM PST, they will receive 16 additional packs. (33% of 47 affected packs)

This fix will also be added to the release of Mean Streets of Gadgetzan before packs are available to open in all other regions, so players will not be affected by this bug when Mean Streets of Gadgetzan goes live in their region.

We are currently working on when the compensation will be applied to affected players. We will provide additional updates as they become available.

Thank you for your patience and understanding as we worked to resolve this issue as quickly as possible.

 

As a comparison point, Kripparrian, the popular Hearthstone streamer who makes a living out of opening packs and never hitting his disenchant button has more than 170 copies of Kabal Chemist already, more than any other card in his collection and it's a Rare. Even if he's opened 400 packs today, he has not hit the disenchant button in years through multiple releases and he already has more than every other card. If he knocks down the requirement to 150 it's still made up entirely of the new tri-class cards. Needless to say, there's certainly something wrong.

It is unknown whether any kind of compensation will be made to those who have already opened their packs and dusted their duplicates.

We opened our packs earlier today and did notice more of these cards than usual.
