This isn't exactly a bug but I believe it's something that needs to be "fixed" in a sense. Right now Warrior and Paladin are the only two classes that wear Darklight that requires Both Head and Chest slots to be taken up and both legs and boots. This causes a problem I and many other tanks have noticed. The problem is that when purchasing Artifact +1 you CAN NOT equip it until you have obtained the other piece as well. Every other class get's to purchase their first Artifact piece and equip it but both Warrior and Paladin can't. Example. If I am wearing Heavy Darklight Armor (which is the best prior to AF+1) it takes up my Head/Chest. If I purchase my Head AF I can't equip it because I have Heavy Darklight on. I can't equip my Heavy Darklight because AF+1 + another piece isn't as good as Heavy Darklight. So in order to get the benefits of AF+1 Tanks need both Head and Chest, and Legs and boots, before equipping the artifact.

In the long run it's exactly the same amount of mythology, I understand. But it put's Warrior/Paladins 2 weeks before everyone else getting to equip their artifact pieces. They need to separate Heavy Darklight just like they do with every other class. Head, Chest, Gloves, Legs, and boots all need to be separate. It's a cool idea but it is flawed.
