Its that time again
We're just a few days from the annual Cyber Weekend sales, and like clockwork comes the question that keeps getting asked, year after year after year.
Does Kabam nerf units in the arena crystals before J4/CW?
Answer: no.
For the past few years I've been opening arena crystals in batches of one million BC worth, first UC and then TB crystals, and recording (like in a spreadsheet, not in video form) all of those crystals. Here's my stats for all openings leading up to Big Sale days.
July 3, 2020: 2850
November 15, 2020: 2625
July 2, 2021: 3000
November 2, 2021: 2250
November 20, 2021: 4125
June 14, 2022: 2625
June 25, 2022: 1500
November 13, 2022: 2250
Note: the statistical designed average for one million BC of UC crystals (100) or TB crystals (20) is the same: 1800 units. That's what the crystals will drop over the long run at the odds they are programmed with.
If anything, my openings leading up to Big Sale days are statistically higher than average, not only relative to the designed odds but also relative to my own long term overall arena crystal averages. Across all UC crystals I recorded, my average was 1926 units per hundred crystals. To date, my TB average is 2017 per hundred crystals (this is skewed upward by one gigantic October opening where I got 5250 units in 20 crystals, which is my all-time highest per million BC result).
If Kabam was nerfing these crystals, I could still get lucky. Once, twice. But if they were nerfing them as severely as some people have suspected, then the results above would be statistically almost impossible. The reason being: they cannot nerf the quantities. That would be easy to detect. So they would have to nerf the odds of dropping. But the odds per crystal are fairly low to begin with (15% overall). To nerf these odds in a noticeable way to players, the resulting statistical change across a sample size of eight million BC worth would be noticeable and difficult to escape by chance.
So: no. Units are not nerfed in the weeks before Big Sale days. It is still just luck.
