For a few players, there could be a tricky situation at the Great Vault just after Season 3 starts this week, and it needs some explanation.
As we previously explained, the thresholds required to qualify for Great Vault rewards are lowered in Season 3. These lowered thresholds will first apply to the Vault after the completion of the first week of Season 3 activities, which is next week.
However, the UI for this has now been updated. What this means is: it’s possible to have completed 8 Mythic+ Dungeons last week (Season 2) and see that the Great Vault is not offering you a reward, even though it says 8 Mythic+ Dungeons in the tooltip, because for the last week, the reward still requires 10 Mythic+ Dungeons.
Good luck with your final rewards from Season 2!
