Additional Considerations Data as of April 10, 2017

Analysis Bias

This table shows how heavily the calculated legendaries drop rate depends on the data that is considered. If we include data from users that have added less than 100 packs per set, the legendaries drop rate - especially for Un'Goro - decreases.

The most likely explanation is that people who have entered fewer packs have not triggered their pity timers yet, however it's theoretically also possible that Blizzard has changed the pity fuction from set to set.

Packs Threshold	Classic	TOG	MSG	Ungoro
Legendaries per 1000 packs as a function of the packs threshold used for analysis
100	56.9	53.2	52.4	52.6
50	57.6	53.3	51.8	51.5
30	57.4	53.4	51.8	50.6
10	57.7	53.4	51.5	49.3

Statistical Significance

As you can see here, the distribution of legendary drop rates for individual users is a lot sharper for those who have opened at least 200 packs, as opposed to those - in this case - who have opened 50-100 packs.

In conclusion, the less packs you open, the more likely you are to get lucky or unlucky. The more packs you open, the more closely your drop rate will approach the expectation value.
