I think what he is saying might be misinterpreted here. Listening to what he said, it sounds like to me that the artifacts get drained as part of the 110 bfa quest lines. Which would make sense, they don't want artifact weapon talents stacking with the bfa talents. It wouldn't make as much sense to remove the talents for legion level questers since legion level items don't have talents. He specifically used the word drain and we already know the weapons are used to treat the wound in silithus. I'm guessing they lose their artifact power as result of that treatment and we just carry the husk after.
At any rate, I'm not sold based on what he said that the artifacts are nerfed at every level.
It would also require quite a bit of alteration in legion loot , follower quesrs, and questlines to disable ap entirely. Since its a central theme of the legion era activity.
I just had a listen myself (link to the video here at the correct spot https://www.twitch.tv/videos/239064071?t=46m19s). I do hope your correct, I hope they dont disable traits on login one day lol
