Evoker Class and Legion Quests

I know it’s just a game, and we can wave our bronze-dragonflight magic at anything. But, Evokers weren’t around canonically during the events of Legion. Like you pointed out, the artifact weapons were a huge lore point during the events of legion (so this isn’t like DH going back to Pandaria, because the class of the champion had nothing to do with the events of Pandaria). So like retconning a new artifact weapon and class hall and NPCs into the old story feels kinda “bad” to me.
