я наткнулся на топик, в котором автор пытается подсчитать, сколько бустеров требуется открыть для того, чтобы собрать полный сет для ККИ ХС и Faeria -
Calculating the worth of the full core collection option (self.faeria)
автор Tigrosaur
"Greetings everyone,
Today I'd like to talk with you about the simple question:
How much is the full core collection option cheaper than buying booster packs ?
Let's investigate!
For the following calculations I'll use the crafting system from Hearthstone and assume Faeria's will be similar or equal when it comes out.
To avoid confusion with the different namings I'll use Faeria's names here.
The first set of Hearthstone cards ("Expert Set") contains 245 collectible cards:
94 Commons (188 for a full collection)
81 Exceptionals ("rare" in Hearthstone's terms; 162 for a full collection)
37 Rares ("epic" in Hearthstone's terms; 74 for a full collection)
33 Legendaries
Using the refactored rarities, software engineers developed programs to compute the amount of packs required for a full (non-golden) Hearthstone collection (2 of every card, 1 of every legendary) by also taking advantage of the crafting system:

As you see you'd need around 460 Hearthstone packs on average.
How do these numbers translate into Faeria?
Well, Faeria's collection contains 256 unique collectible cards:
106 Commons (318 for a full collection)
68 Exceptionals (204 for a full collection)
61 Rares (183 for a full collection)
21 Legendaries
While in Hearthstone you only need two of every non-legendary card we need three in Faeria !
It doesn't take long to obtain all commons and exceptionals, however rares and legendaries are the real catch here.
In Hearthstone's crafting system a legendary card is worth approximately 4 rares, a rare card approximately 4 exceptionals and one exceptional approximately 4 commons.
Using this we can calculate the value of a full collection using the following formula:
43 * (# of legendaries) + 42 * (# of rares) + 41 * (# of exceptionals) + 40 * (# of commons)
Hearthstone's full collection: 43 * 33 + 42 * 74 + 41 * 162 + 40 * 188 = 4132
Faeria's full collection: 43 * 21 + 42 * 183 + 41 * 204 + 40 * 318 = 5406
Earlier we said that a full Hearthstone collection needs 460 packs on average.
Using simple math and the numbers above we can calculate that a full Faeria collection requires 460 * 5406 / 4132...
about 600 packs on average!"
Вывод автора - потребуется порядка 460 бустеров для ХС и 600 бустеров для Faeria, кстати в последней можно купить full set за 50$
"As the price of a single booster pack is $1, we can finally say that the full core collection option is indeed worth $600
So if you were buying the full core collection you'd safe 91,7%!"
