Azerite Armor From Emissary Quest Has Wrong Item Level

The item level of Emissary quest rewards changes depending on your own character's item level.

Following the release of new raid content, we may increase the maximum item level of gear that Emissary quests can award. However, this does not mean rewards will always be of that new level. Your rewards will still be based on your character's item level history, up to the maximum we've set for Emissaries.

Because Azerite Armor goes up by 15 item-level increments, if your character's item level is not high enough to receive the highest tier of rewards yet, the item level of your Azerite Armor rewards will be at least 15 item levels lower than the maximum. This is working as designed.
