Yeah, these quests show up even earlier, at level 102.
I'm wondering if there is even a point in consuming artifact power items before 110 and acquiring artifact knowledge. Thoughts?
Edit: Nvm. I just found this at WowHead:
"Artifact Knowledge WILL NOT boost the Artifact Power granted by any items in your inventory that were obtained BEFORE you reached a certain Artifact Knowledge level.
For the above reasons, it is not worthwhile to stockpile Artifact Power items, hoping to use them after you level Artifact Knowledge."
PSA, I guess.
