Be fair I've been RPing for a very long time. A good chunk of that was in a guiding, teaching role for the community. Stuff like that, to me, smells of Mary Suedom and plot breaking for the sake of making one's character more interesting, though ironically in a very superficial way, as your character would still be blasé. It's the item which would make them more 'interesting,' rather than the intrinsic value of the character.
But at the same time... if you know and don't care... no skin off my nose. Just be aware of which circles care and which don't.
Well I'm probably just going to have the model for the Brewmaster keg staff and call it my walking staff with a keg on it. Force it to be generic. As for everyone else, I actually can ignore them all! Every part of Warcraft is something that any other player can do. That includes boss kills, questlines, things like garrisons... so much of WoW's story, one-off quests and boss kills, are presented as the significant work of just one person, or a group of 5 to 25/40. And yet, there are far more people who have accomplished these feats than could ever possibly be justified in RP. You could never fit the number of people who have bested the Lich King on the platform you fight him on, for example. When there are many many more roleplayers out there, thinking of how to rationalize all of this becomes an impossibility.And I have a question for you: how YOU gonna explain it? - Your weapon and seeing all other artifacts? :P You cant just ignore all of them
So the truly good roleplayers ignore it. They see the quests they do as the backdrop from which backstory emerges. The boss kills are rendered taboo for players to claim and thus are performed by some group of anonymous adventurers and heroes. While my Brewmaster might not be the Commander on Draenor, she could still have participated as a soldier if I wanted her to. As a member of the "Sea of faces," or in layman's words, as a character who could be interchangeable or even removed from the plot entirely without any change to the narrative.
It'll be the same with artifacts.
