Hi everyone! Thanks for your feedback, wanted to drop in a few updates/notes.
In the next build, you'll see that the required currency for each bonus item has dropped from 10000 to 1000 Order Hall Resources. We agree that the "hard part" of getting the bonus items should be maxing out your artifact, not the grind afterwards.
In 7.2, we want these bonuses to feel like a badge of honor for players that have unlocked the final ability on their empowered artifact. For some time they'll be pretty exclusive, and this is intentional. It makes sense for the Blood Death Knight, with their bloody mount, to also have the Bloodbrood Whelpling, showing off their dedication to their specialization.
It's also important to note that we also have no plans to remove these items in the future, and we will re-evaluate their acquisition in a post-artifact world. If you don't want to go for them right now, don't worry, you won't be permanently missing out on anything.
I hope this assuages some of your concerns. As always, we're looking forward to your continued feedback!
