So one of the first things you get is your artifact and its 730ivl.. So not very useful
Raid Spec is Healer/Tank , but leveling DPS?
From what I hear is you can get your second spec artifact at 102, so still not very useful..
IE:
1. Get DPS artifact and at level 102 get Healer/Tank Artfact and save all Artfact power turnins for raid Spec.
So I guess it's for transmog or "Current Raiding"
