The shortest of these durations since WoD was 41 days (Patch 7.1.0 in Legion), and the longest was the 99 days it took for the last major patch of Battle for Azeroth to hit Live servers. What does this data show us? Primarily, it shows us that there has not been much consistency over the years on how many days pass between a major content patch hitting the PTR to it being released on Live servers. Keep in mind, these past expansions did not take place under the thumb of a global pandemic, so that may skew our expectations slightly.ĭates and information sourced from Wowpedia We started this look through the history books in Warlords of Draenor and worked our way back to the current expansion. While this data is by no means conclusive, we thought it might be interesting information to estimate what kind of timeframe we may be looking at for 9.1. We decided to look back at the past few expansions to get an idea of the average length of time Blizzard typically takes between releasing a major content patch on the PTR, and then releasing the patch on Live servers.
