The title says it all, someone with better math skills please let us know! It just happened to me with my 4000pt season reward 10 pack.
Probably not as bad as you think. It is about 1 in 6.
At a 79.3 rate of failure (the 2 star total odds), 9.83% of 10 packs will contain no 3 or 4 stars. Here’s the breakdown:
9.83% - 0 covers
25.67% - 1 cover
30.15% - 2 covers
20.99% - 3 covers
9.59% - 4 covers
3.00% - 5 covers
0.65% - 6 covers
0.10% - 7 covers
0.01% - 8 covers
5.53358x10^-6 - 9 covers
1.44445x10^-7 - 10 covers
Not sure whether I should have calculated using rate of failure (79.3) or the rate of success (21%) because of the hidden rounding, but the numbers should be fairly similar. Sorry to hear about your pack-best of luck on your next 10 pack!
The other day I opened all my saved heroic tokens, 64 I think it was (I saved some for some other moment where I could need the iso), and these were my results:
1 yellow colossus
1 yellow storm
1 black the hood
1 green XForce
1 red CA
1 green LThor
1 yellow LThor
1 red Psylocke
56 2*
I had a ratio of 12.5%, which is a little bit less of the average, so you can say I had bad luck. And at some point I think I opened more than 10 heroic tokens without pulling any 3* or 4*
Chances of getting a 3* or 4* should be far higher, it is really difficult to pull something good from a token (in my case just one yellow colossus). I would never in my life buy an heroic token, it is wasting your HP (money)
PS: When you are oppening heroic tokens the ratio of failure is 84% - (there are 11 2* with 7.2%, and 1 with a 4.8%), worse than when you open 10-packs… In that case you have a 17% chance of not pulling any 3* or 4* (more than 1 of 6 which is a lot)
