Sadly I opened two packs of three already. But this time it’s a real issue, not just a bad luck thing. We spent actual real money for that and didn’t get what we paid for.
The drop rates stated are correct.
The calculation of the Best is the inverse of the Light multiplied by itself twice.
For the Light Mythic drop rate: 100% less 16.09% equals 83.91%.
83.91% times 83.91% times 83.91% equals 59.08%. This is the chance of not getting a Mythic from an Historic Bundle Best.
Therefore, the Best Mythic drop rate is 40.92% as stated.
sjechua’s right; they’re correct (or at least consistent with each other). The key is that the “historic bundle best” drop rates in the shop are your odds of getting 1+ cards of a rarity after opening all 3 packs (which it says on the screen showing the percentages). Once you have the packs in the vault, it looks like it shows the odds of getting 1+ cards of a rarity from opening just one of the three packs. The numbers have changed because it’s the odds of a different thing, but the probabilities are consistent.
If drop rates were displayed in terms of odds per card, then it’d stay the same no matter how many packs were involved or how many cards per pack; I guess they picked odds per pack (or per bundle) because higher numbers make it look like better value.
Well, each thing they displayed seems to have been displayed correctly, but that doesn’t mean it wasn’t confusing. E.g. it might be easy to see the drop rate per bundle (40% chance of 1+ mythics) and mistake it for the drop rate per pack (16% chance of 1+ mythics).
Nah, it’s right, that’s what sjechua was trying to say.
Think about it this way, if the chance of 1+ mythics from 1 pack is 16%, what’s the chance 1+ mythics from 10 packs? It’s not 10 x 16% (160%). It’s not even 100%; it’s possible to open 10 packs and get no mythics. What it is is 1 - (1 - 16%)^10, or around 83%.
