What is the correct way of labeling artifact armor?

[Krystalynn]

so when the real AF2 comes out what are you gonna call em? Stop confusing ppl!

AF3? Not that hard. It's only 'real' to you because you decided it to be. The images shown by the team of content in development is the second model set created by the team. As far as the artists go, it is AF2 because it is the second model designed by them for the purpose of being tier sets, however the player does not see this visibility.

Let's take the look of the set completely out of the picture. Artistically, let us remove the entire model from the discussion. Let us look at the item itself, from one tier to the next and stack them beside each other. Then what the game tells us functions as the +1 mechanic.

For Curtana to be +1, as an upgrade, it requires Curtana and a regeant. The item is then destroyed, and given in a new state called Curtana +1. This means this is now a +1 Relic weapon.

Does this criteria apply, to our current AF1 set? Does it? So what is it we buy with Myth? Seems like an entirely new, named set to me. It doesn't even share the same name or stat scheme.

This is a new tier of AF armor. It is AF2. To think otherwise is to confuse yourselves.

As for the developer concept sketch?
