How many packs are you considering within these freebies that are available during expansion launch?
It varies from expansion to expansion, but generally speaking Blizzard has been giving away between 6 to 9 packs as freebies that players can get on release day or very quickly thereafter.
As someone who for several expansions now has opened at LEAST 140 packs on launch day, those first 80 or so packs (in every expansion in 2018) were a very far cry from the results you’re claiming here.
I have the data sheets of my results for every expansion going back to Goblins & Gnomes. For every expansion where I have followed my plan (70-80 free packs + freebies) I have had similar results which provide these averages…
Commons: 98/98 (100%)
Rares: 71/72 (98.61%)
Epics: 33/54 (61.48%)
Legendaries: 11.6/23 (50.43%)
TOTAL: 213/247 (86.56%)
DUST FROM DUPLICATES: 2,800
On launch day the pack-opening binge generally lands me close to 75% to 80% of the cards, and slow-roll crafting as the meta unfolds using dust from the duplicates gets me to 86%. I could get to that 86% on day one if I just crafted immediately, but I prefer to wait and see what matters before I spend any dust.
At 80 packs I was still only on legendary #4 (this is WITH the free one upon login)
I’ve never had a result that poor. Blizzard gives a free Legendary out, and then you get one in the first 10 packs. Are you really saying that in 70 packs after that you’ve only averaged 2 Legendaries? You’re the unluckiest sod, and you have my pity. My average is more along the lines of 1 Legendary every 15-20 packs, so I typically end up with 7-8 Legendaries from the pack opening alone and then I craft 1-2 more as the meta unfolds. More if dust refunds happen from nerfs.
not to mention my spare dust from duplicates alone being less than 2k each time.
Maybe you aren’t as aggressive as I am. I dust all duplicates, and any Golden card as well that I have all the ‘basic’ versions of. Some people don’t dust their gold extras. To me they’re nothing but fuel for stuff that matters.
